Release 2026.08.02-1

SQLite replaces Postgres, and two fixes from using the thing.

- The database is a file under ./storage instead of a second container. Ten
  members never needed a database server, and the driver is pure Go, so the
  build stays CGO_ENABLED=0 and the dependency count is unchanged. One bind
  mount is now the whole backup: no pgdata, no healthcheck-gated depends_on,
  no startup retry loop. Timestamps are UTC text, idle_ttl is seconds, the
  divisive/unified boards carry their own stddev, and foreign keys are on by
  pragma. Tests get a database file each and run without any setup
- Invites are copied, not clicked. An invite is something to send, and the
  anchor opened the join form in the admin's own browser
- Feedback asks for more than faults: the footer reads "Ongelmia? Ideoita?
  Palautetta?" and the page behind it invites ideas rather than only bugs
- Kuuntele YouTubessa opens in a new tab, so a half-typed review survives it
