feat(ui): allow arrow keys and space during search filtering

- Modified FORCE_CHAR mode in read_key() to recognize arrow keys and space
- Users can now navigate and select items while typing in search mode
- Improves UX by eliminating need to press Enter before selecting
- ESC key still works to cancel search

This restores V1.19.0 behavior where navigation worked during search
