Closes #5. Three of the server's tunables were environment variables,
which meant changing how long an incident waits before being paged again
required editing a chart, merging it and waiting for a reconcile. They
are behaviour rather than infrastructure, and the difference is who needs
to change them and how often.

The split is by who owns the value. What stays in the environment is
where the server is plugged in: the listen address, the DSN, the ntfy URL
and token, the public URL. Those are needed before the database is open
and two of them are credentials -- the settings endpoint reports that
ntfy is configured and that a token is set, and never what either is.

What moves is how it behaves: the notify repeat interval, the stale
window and the archive window. The environment variable becomes the seed
rather than the setting, written once on first start and never
overwritten, so a redeploy cannot put a chart's default back over an
administrator's edit -- the rule the per-team dead man's switches already
follow. The loops read the current value per tick, so a change at 02:00
is obeyed at 02:00.

Key/value rather than a column per knob: #6 and #7 will both add
settings, and a table shaped one-column-per-setting needs a migration for
each. The cost is that values are text and the accessor has to say what
type it wanted, which settings.go does in one place. Unknown keys are
refused rather than stored -- a typo that wrote notify_repeat_second
would otherwise sit in the table looking like configuration and doing
nothing -- and each value has bounds loose enough to catch a slipped
decimal point without having an opinion about anybody's rota.

Disabling an account is new, and is not deleting one. Deleting a user
nulls acknowledged_by and assigned_to, which quietly rewrites who did
what during an incident months after the fact. A disabled user cannot
authenticate by either credential, loses their sessions immediately, and
stays the name on every acknowledgement they made. The check is part of
the lookup in serveAs rather than a test afterwards, so there is no path
where the row is loaded and the flag is then forgotten.

The page itself is a fourth tab, shown only to an administrator and only
as a courtesy: every endpoint under it is refused with 403 regardless, so
somebody who types /admin gets an explanation rather than a blank screen.
It lists teams with their size and open-incident count, users with their
flags, and the settings with their bounds -- plus the environment half,
read-only, so somebody hunting for the ntfy URL learns where it lives
instead of concluding the server has none.

Delete is disabled rather than offered-and-refused for a team with open
incidents, and neither admin action is offered on your own account, since
the server refuses both.

Niklas Ye a4fbd60441 Scope everything to a team, and route alerts by integration key
CI / chart (pull_request) Successful in 1s
CI / security (pull_request) Successful in 13s
CI / test (pull_request) Successful in 1m49s
The core of #4, and what #1 is for: terdut stops being one shared space.
A team owns its incidents, alerts, schedule and integrations; a user sees
exactly the teams they are in. Everything that existed moves into one
Default team and every existing user becomes an owner of it, so the
upgrade is a no-op for the people using it.

Ingestion is the load-bearing half. An alert arrives on a team's
integration key, and the key is both the credential and the routing: it
says that the sender may post, and which team the alerts belong to. That
also closes the unauthenticated webhook -- the old path stays for one
release, deprecated and routed to the oldest team, so an upgrade does not
stop delivering while somebody edits the Alertmanager config.

Scoping is enforced in as few places as possible, because the failure
mode is silent. serveAs loads the caller's memberships once; list queries
carry `team_id = ANY(...)`; and every incident route goes through
incidentIDParam, which now parses the id AND checks the team in the same
call, so a new handler cannot remember the first half and forget the
second. Anything in another team is 404, never 403: whether an incident
exists is that team's business.

Two bugs this found, both of which would have been silent:

  * upsertAlerts decided "is this a new occurrence" by looking up the
    fingerprint alone. Across teams that made team B's first alert look
    like a re-send of team A's, so it opened no incident at all. The
    lookups are keyed on (team_id, fingerprint) now, as the index is.

  * Every uniqueness rule was written for one tenant. Two teams watching
    two clusters legitimately see the same fingerprint, the same
    groupKey, and want somebody on call on the same day; all three
    constraints move to include team_id.

Roles inside a team are separate from the system administrator flag: an
owner configures the team, a member works its incidents, and an admin is
NOT implicitly in every team -- administration is about accounts, not
about reading other people's incidents. An admin can still repair a team
whose owner has left, which is why requireTeamOwner lets them through.

A shift can only be given to somebody in the team. Paging a person who
cannot open the incident is worse than paging nobody.

The UI is updated only as far as keeping it working: it loads the
viewer's teams with the session and uses the first one, since nobody has
a second yet. "On call now" shows every team the viewer is in, named only
when there is more than one, so the common case reads exactly as before.
The team switcher, badges and per-team settings pages are the next step.

Breaking for API clients: the schedule endpoints moved under the team,
and /api/schedule/current returns an array rather than an object or a
404. terdut-tui will need a version for that.

Per-team dead-man configuration is deliberately not here. A heartbeat's
incident already opens in the team whose key received it, which is the
part that matters for isolation; moving the matchers out of env into
per-team rows is a change to how deadman.go is configured rather than to
who sees what.

Niklas Ye dc39e3a5d3 Move the database to Postgres, before teams need the schema
CI / chart (pull_request) Successful in 1s
CI / security (pull_request) Successful in 17s
CI / test (pull_request) Successful in 2m5s
First step of #1, and it goes first for one reason: #4 adds a team_id to
nearly every table, and doing that twice -- once for SQLite, once for
Postgres -- is work nobody gets paid for. The teams migrations now only
have to be written against one database.

The ten SQLite migrations are replaced by a single Postgres baseline
rather than ported one by one. They were incremental in a way that has
no value on a fresh install: 004 adds columns 008 drops again, and 008's
backfill rewrites data a Postgres database never had. The history stays
in git; the schema they add up to is now 001_baseline.sql.

Timestamps stay BIGINT unix seconds and are NOT converted to timestamptz.
Everything in Go already speaks epochs, so converting would have been a
second, larger change riding along inside this one. It is worth doing on
its own. The JSON columns did move to jsonb, because #4 will want to
filter and index on labels.

Most of the port is mechanical -- 170 placeholders from ? to $1 -- but
four things needed more than a search and replace:

  * Dynamically built WHERE clauses cannot keep their numbering straight
    by hand, so they hand out placeholders through sqlArgs instead. A
    filter can now be added or reordered without renumbering anything.

  * SUM(resolved_at IS NULL) was SQLite counting a boolean as 0 or 1.
    Postgres has no sum(boolean), and this was breaking every dead man's
    switch -- silently, since the sweeper only logs. Now COUNT(*) FILTER.

  * unixepoch() became FLOOR(EXTRACT(EPOCH FROM now()))::bigint. The
    FLOOR is load-bearing: a bare cast rounds half up, so a row written
    at .6 of a second claimed a timestamp a second in the future and
    disagreed with the time.Now().Unix() the Go side stamps.

  * The unique-violation check matched SQLite's error text. It matches
    SQLSTATE 23505 now, so a renamed constraint cannot turn a 409 back
    into a 500.

Tests need a real Postgres, because there is no in-memory Postgres the
way there was an in-memory SQLite. Each test gets its own schema on a
shared server -- cheaper than a database each, and still isolated.
TERDUT_TEST_DSN says where it is; `make test-db` starts one locally and
ci.yaml runs one as a service container. An unset DSN fails the suite
rather than skipping it: a run that quietly tests nothing is worse than
one that does not run.

TestMigration_BackfillCarriesAckAndComments is deleted along with the
migrations it replayed. What it protected -- an upgrade not losing
acknowledgements and comments -- now belongs to scripts/sqlite-to-postgres.go,
which is build-tagged so the SQLite driver stays out of the server
binary. Both are meant to be deleted once this install has migrated.

The chart loses the PVC, the data volume and the python backup sidecar,
and requires database.dsnSecret.name: it provisions no database and
cannot guess where the credentials live, so a render without it is meant
to fail. Backups move to where Postgres actually runs. The other half of
that -- the postgresql CR, the k8up pg_dump annotation and the network
policy -- is a change to the wrapper chart in Ryuvia/charts and is not in
here.

Verified rather than assumed: the gate is green with -race against
Postgres 17, govulncheck and gitleaks are clean, and the migration script
was run end to end against a SQLite database built at the old schema and
seeded in every table. Ids survive, so incidents keep their numbers and
every foreign key still points where it did; the identity sequences are
moved past the copied ids, and a webhook after the migration opened
incident 12 rather than colliding at 1.
