Prowlarr non-category search fallback, bypass optimizations, and code cleanup (#379)

- Prowlarr: Added automatic fallback to search without category filter
when indexers return no results with book category (7000), improving
compatibility with indexers that don't support category filtering
- Prowlarr: Hide language filter in UI since Prowlarr has unreliable
language metadata
- Bypass: Refactored internal bypasser with code cleanup, extracted
helper functions, and added health check capability
  - Bypass: Added fingerprint module for screen size handling
- qBittorrent: Fixed connection test to use web API version instead of
app version
- Frontend: Added supported_filters config to control which filters
display per source
- Auth: Improved CWA database path validation (now uses Path object
properly)
