Fix item visibility bugs and add effects web UI

- Fix recipe filter to allow owner=None (S-expression compiled recipes)
- Fix media uploads to use category (video/image/audio) not MIME type
- Fix IPFS imports to detect and store correct media type
- Add Effects navigation link between Recipes and Media
- Create effects list and detail templates with upload functionality
- Add cache/not_found.html template (was missing)
- Add type annotations to service classes
- Add tests for item visibility and effects web UI (30 tests)
