Add comprehensive Bluesky tests to posts_helper_spec

- Add extensive test coverage for Bluesky user profile URL matching
- Test handle-based and DID-based profile URLs with various formats
- Add edge cases and error condition tests for malformed URLs
- Test user avatar icon path and model path generation
- Verify fallback behavior for users without display names
- Test priority logic for handle vs DID lookup
- Add tests for special characters and very long handles
- All 82 tests now pass successfully
