feat: add editable search input to Prowlarr modal with scrollable badges

- Add text input for custom search queries in Prowlarr modal
- Quick search badges pre-fill the input and trigger search
- Default query uses quoted series name for exact match
- Add custom_query support to backend API
- Limit badge area height with vertical scroll
- Add debug logging for Prowlarr API responses
