refactor(ui): simplify filter preset empty state

- Remove default presets and restore defaults functionality
- Unify preset UI: always show '+ Add' button regardless of preset count
- Remove empty state message and restore button to reduce visual clutter
- Clean up unused translation keys (restoreDefaults, noPresets)
- Fix spacing issues in filter panel
