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 Refs #CI-run-19 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
