feat: add expanded visual view for filter rules

- Add VisualRuleSummary component showing conditions and actions as
  labeled inline pills with IF/THEN flow layout
- Add expandedFilterView toggle to settings store (persisted)
- Fix RuleSummary to allow multi-line wrapping instead of truncating
- Use items-start on rule cards so drag handle and toggle align to top
- Add translations for expanded view keys in all 8 locales
