fix: WOPI registration on restart + Collabora readiness probes

- Add readiness/liveness probes to Collabora (GET /hosting/discovery)
- Add init container to Drive backend that waits for Collabora and runs
  trigger_wopi_configuration on every pod start — fixes WOPI silently
  breaking after server restarts (chart Job only ran on sunbeam apply)
- Add OIDC_RESPONSE_MODE=query to Projects config
