fix(ui): restore real-time search filtering in paginated menu

- Previous perf optimization (318c67f) broke real-time search by removing rebuild_view call
- Now calls rebuild_view and triggers full redraw when typing/deleting
- Uses 'continue' to skip drain_pending_input, preserving fast typed characters
- Fixes issue where only first character was effective in search
