fix: regressions found by the test suite

- TrustHosts: validate the Host header also when the FQDN cache is cold.
- Settings email: authorize the SMTP and Resend toggles.
- Server navbar: show Sentinel status only to users who can view Sentinel.
- GitHub source: restore permission gates on Sync name and Delete, and the
  Test connection button.
- Profile: make avatar upload work (missing import and file uploads trait).
- API tokens: keep the "Never" expiry choice.
- Environment variables: show validation errors instead of a generic error.
- Servers API: read the server uuid from the route in domains_by_server.
- Configuration diff: report all settings when no earlier snapshot exists.
- Cloud servers: restore Power On for stopped servers; do not repeat the
  provider error prefix.
- HasSecretManager: do not stop later deleting listeners.
- GitLab webhook: use new_public_id() like the other webhooks.
- Dev: show the Lima VM start command on the localhost server page.
