Initial commit — Drive, an S3 file browser with WOPI editing

Lightweight replacement for the upstream La Suite Numérique drive
(Django/Celery/Next.js) built as a single Deno binary.

Server (Deno + Hono):
- S3 file operations via AWS SigV4 (no SDK) with pre-signed URLs
- WOPI host for Collabora Online (CheckFileInfo, GetFile, PutFile, locks)
- Ory Kratos session auth + CSRF protection
- Ory Keto permission model (OPL namespaces, not yet wired to routes)
- PostgreSQL metadata with recursive folder sizes
- S3 backfill API for registering files uploaded outside the UI
- OpenTelemetry tracing + metrics (opt-in via OTEL_ENABLED)

Frontend (React 19 + Cunningham v4 + react-aria):
- File browser with GridList, keyboard nav, multi-select
- Collabora editor iframe (full-screen, form POST, postMessage)
- Profile menu, waffle menu, drag-drop upload, asset type badges
- La Suite integration service theming (runtime CSS)

Testing (549 tests):
- 235 server unit tests (Deno) — 90%+ coverage
- 278 UI unit tests (Vitest) — 90%+ coverage
- 11 E2E tests (Playwright)
- 12 integration service tests (Playwright)
- 13 WOPI integration tests (Playwright + Docker Compose + Collabora)
