fix: address PR #1 security review — drop platform seeds, seal db passwords

- Remove managed connection seeding: platform-postgres/dragonfly carried
  the backend's own DATABASE_URL/DRAGONFLY_URL into tenant projects where
  any member could run arbitrary DBX queries against core tables
  (Codex P1). NewPlatformService loses the seeds param; firstPartyDBSeeds
  deleted.
- Seal db_connections passwords with the existing AES-256-GCM encryptor
  (enc:v1:<b64> marker); decrypted only in dbxArgsFor. Legacy plaintext
  values still read, but migration 00008 strips them (Codex P1).
- Migration 00008: delete is_managed rows, drop plaintext password keys.
- dbxConnectionName uses the full project UUID — the 8-hex prefix could
  collide and alias another project's credentials (Codex P2).
- ci.yml triggers on master, not the nonexistent main/develop branches.
- demo-mode stubs renamed to user-managed connections; CHANGELOG notes
  under Unreleased.

## [Unreleased]
### Security
- **Managed platform connections removed** — `platform-postgres`/`platform-dragonfly` seeds carried the backend's own `DATABASE_URL`/`DRAGONFLY_URL` into every project, where any member could run arbitrary queries through DBX against `core` tables. The seeds are gone and migration 00008 deletes existing managed rows. Operators keep direct `psql`/`redis-cli` access.
- **Connection passwords encrypted at rest** — `core.db_connections.config.password` is now AES-256-GCM sealed (`enc:v1:` marker) via `PRIMORA_ENCRYPTION_KEY`; decrypted only when registering the connection with DBX. Migration 00008 strips pre-existing plaintext passwords.
- **DBX naming** — connection names now prefix the full project UUID; the previous 8-hex prefix could collide across projects and alias the wrong credentials.
