test(communities): Update tests for single handle field
Update all community tests to use DNS-valid atProto handles instead of
scoped handle format. All tests passing including E2E, integration, and
unit test suites.
Changes:
- Update test fixtures to use DNS-valid handles
- Remove atprotoHandle references from test data
- Rename TestCommunityConsumer_AtprotoHandleField to TestCommunityConsumer_HandleField
- Update test assertions to expect DNS format handles
- Fix unused variable warnings in unit tests
Test coverage:
✅ E2E tests (5.57s) - Full PDS → Jetstream → AppView flow
✅ Integration tests (4.36s) - 13 suites covering CRUD, credentials, V2 validation
✅ Unit tests (0.37s) - Service layer, timeout handling, credentials
✅ Lexicon validation (0.40s) - All 60 schemas validated
Example test data changes:
- Before: handle="!gaming@coves.social"
- After: handle="gaming.communities.coves.social"
