folder tree sidebar item, full vitest test suite (55 tests, 4 files), and
commits all Phase 4 backend/frontend fixes that were staged but uncommitted.

Bugs fixed:
- minio_backend.py: generate_presigned_put_url and presigned_get_url used internal
_client (minio:9000) instead of _public_client (localhost:9000). Browser received
ERR_NAME_NOT_RESOLVED. Fixed by using _public_client with region='us-east-1' to
skip region-discovery HTTP request from inside the container.
- docker-compose.yml: MINIO_API_CORS_ALLOW_ORIGIN was set from CORS_ORIGINS which
uses pydantic JSON list format '["http://localhost:5173"]'. MinIO expected a plain
string and never matched the origin. Fixed to use FRONTEND_URL instead.
- admin.py: All write handlers (create_user, update_user_status, update_user_quota,
update_ai_config) used session.flush() without session.commit(). Changes appeared
to succeed (response reflected in-memory state) but rolled back on session close.
Fixed by replacing flush() with commit() in all four write handlers.
- auth.js: Concurrent refresh() calls from QuotaBar and App.vue on page reload caused
a token rotation race — first call rotated the cookie, second arrived with stale
cookie and cleared accessToken. Fixed by deduplicating with a shared in-flight
promise (_refreshInFlight).
Phase 3 UAT: 9/10 pass. UAT-3 (QuotaBar visual) pending browser confirmation.
