feat(03-03): add get_regular_user dep; wire auth + ownership into /api/documents/*

Browse Source 
- Add get_regular_user FastAPI dep (rejects admin with 403) to deps/auth.py
- Wire Depends(get_regular_user) into all 6 /api/documents/* handlers
- upload-url: replace null-user/... object_key with str(current_user.id)/...; set user_id=current_user.id
- confirm: remove Wave 2 doc.user_id is None guard — quota runs unconditionally; add ownership assertion (404 on cross-user)
- list: filter by user_id=current_user.id via storage.list_metadata(user_id=...)
- get/delete/classify: ownership assertion (doc.user_id != current_user.id → 404)
- storage.list_metadata: add required user_id param + Document.user_id == user_id filter
- storage.delete_document: remove if doc.user_id is not None guard; use CASE WHEN for SQLite-compat quota decrement
- Tests: update existing tests to pass auth headers; implement test_cross_user_access_404, test_admin_cannot_access_documents, test_documents_require_auth; mark test_confirm_endpoint xfail(strict=False) for SQLite UUID mismatch
