chore: update dependencies and minor refinements

- Add communityName color to AppColors for threading indicators
- Update dart:async import to use official unawaited function
- Regenerate feed provider test mocks for latest dependencies
- Remove unused imports from test files

Minor code quality improvements following Dart best practices.
