- Migration 004: acknowledged_by/acknowledged_at columns on alerts,
alert_comments table (FK cascade on delete)
- POST /api/alerts/{id}/acknowledge — stamps authed user + timestamp,
returns updated alert with acknowledged_by username
- DELETE /api/alerts/{id}/acknowledge — clears ack (204)
- GET /api/alerts/{id}/comments — list in chronological order
- POST /api/alerts/{id}/comments — add comment (returns 201)
- DELETE /api/alerts/{id}/comments/{commentID} — own comments only (204)
- All alert queries now LEFT JOIN users for ack username
