test(frontend): comprehensive test coverage improvements and bug fixes

- Raise coverage thresholds to 90% statements/lines/functions, 85% branches
- Add comprehensive tests for ProjectDashboard, ProjectWizard, and all wizard steps
- Add tests for issue management: IssueDetailPanel, BulkActions, IssueFilters
- Expand IssueTable tests with keyboard navigation, dropdown menu, edge cases
- Add useIssues hook tests covering all mutations and optimistic updates
- Expand eventStore tests with selector hooks and additional scenarios
- Expand useProjectEvents tests with error recovery, ping events, edge cases
- Add PriorityBadge, StatusBadge, SyncStatusIndicator fallback branch tests
- Add constants.test.ts for comprehensive constant validation

Bug fixes:
- Fix false positive rollback test to properly verify onMutate context setup
- Replace deprecated substr() with substring() in mock helpers
- Fix type errors: ProjectComplexity, ClientMode enum values
- Fix unused imports and variables across test files
- Fix @ts-expect-error directives and method override signatures
