test: add L2 feature test files for conditional formatting, swimlane persistence, activity feed filters, automation multi-step, and import preview

- ConditionalFormatting.test.ts: Tests evaluateConditionalFormatting for
  operator-based rules, expression-based rules (L2), mixed rules, and
  edge cases
- SwimlanePersistence.test.tsx: Tests KanbanBoard localStorage persistence
  of collapsed swimlane state
- ActivityFeedFilters.test.tsx: Tests ActivityFeed filter badges and
  activity filtering by type
- AutomationMultiStep.test.tsx: Tests AutomationBuilder multi-step action
  numbering, execution mode selector, and condition fields
- ImportPreview.test.tsx: Tests ImportWizard preview row limit (10) and
  validation error detection
