feat(mobile): Containr companion app — Expo/RN thin client

Phone app v1 (Phase I): PAT auth against any instance, secure-store
credentials, dark UI matching the design system.

- Overview: service status counts, per-project health dots, deploy feed
- Services/Projects: status badges, drill-down detail
- Service detail: start/stop/restart/redeploy/sleep/wake, env-doctor
  issues, deployment history + rollback
- Logs: 300-line tail, 5s poll, stderr highlighted
- Databases: status, start/stop/restart, backup-now
- Settings: server info, disconnect

CI: mobile job (tsc + expo lint) gated on a dedicated app/mobile paths
filter so non-mobile PRs skip it entirely.
