fix: complete ORM port — token/oauth-client API mismatches, use published orm 0.2.8

- Use published @simpleworkjs/orm ^0.2.8 (fixes redis adapter write path)
  and model-redis ^1.6.0 instead of a local file: link that broke docker
  npm ci with a misleading "no lockfile" error.
- OtpToken.issue/verify: replace nonexistent find()/listDetail() with
  list({where}).
- routes/auth.js: ImpersonationToken.listDetail() -> list({where}).
- routes/token.js: drop listDetail() call; 404 on missing token instead
  of returning {results: null} with 200 (orm get() returns null, does
  not throw like model-redis Table.get did).
- OAuthClient: Resource has no is_valid column, so every client read as
  disabled and all /oauth/authorize requests 400'd — validity now lives
  in metadata (absent = valid). Also generate a unique slug on create
  (Resource.slug is required+unique) and use Resource.get() for lookup.
- User.login: 401 cleanly when neither uid nor username is supplied.
- models/index.js: log ORM init and surface init failures.
