API responses now include file_url and thumbnail_url fields. When
S3_PUBLIC_BASE_URL is configured, these point to the CDN domain;
when unset, they fall back to the existing API proxy paths so local
dev requires no additional setup. UI updated to use response URL
fields directly instead of constructing proxy URLs client-side.

- Extends GET /api/v1/tags with sort=count_desc and min_count query params
- New TagsComponent at /tags (public, no auth guard) shows all tags sorted by image count
- Clicking a tag navigates to /?tags=<name> for a pre-filtered library view
- LibraryComponent reads ?tags= query param on init to support deep-linking from tag browser
- Library header gains a "Browse tags" link to /tags for discoverability
- All 15 TDD tasks complete; ruff, ng lint, and ng build clean

Make the app title a clickable link to / so users can return to the
image grid from any sub-page without the browser back button. Change
the sign-out destination from /login to / since the grid is publicly
accessible and avoids unnecessary friction post-logout.

- Add Pillow dependency and thumbnail.py with generate_thumbnail() — produces
WebP ≤400px, preserves aspect ratio, never upscales, handles GIF frame 0
- Alembic migration 002 adds nullable thumbnail_key column to images table
- Upload route generates thumbnail via asyncio.to_thread (non-blocking),
stores at {hash}-thumb; failure is tolerated and upload succeeds with null key
- New GET /api/v1/images/{id}/thumbnail endpoint: serves WebP thumbnail or
falls back to original for pre-feature images; ETag + immutable cache headers
- Delete route cleans up thumbnail storage object alongside original
- Library grid switches from /file to /thumbnail for all image src bindings
- 59 tests passing (46 existing + 13 new across unit, upload, serving, delete)
