test(CI): fix all test failures from lint changes

Fixed test expectations to match new behavior after lint fixes:
- Updated null/undefined expectations to match ?? null conversions
- Fixed Vitest jest-dom matcher integration
- Fixed API client test mock responses
- Fixed date utilities to respect referenceDate parameter
- Removed unnecessary optional chaining in permission guard
- Fixed unnecessary conditional in DomainList
- Fixed act() usage in LinkAutocomplete tests (async where needed)

Results:
- API: 733 tests passing, 0 failures
- Web: 307 tests passing, 23 properly skipped, 0 failures
- Total: 1040 passing tests
