fix: archive_read_only creates bare repos for archived announcements

Combined Accept and AcceptArchive match arms in builder.rs to ensure
bare repositories are created for both cases. Previously AcceptArchive
had duplicate code that didn't call ensure_bare_repository().

Also includes:
- Config fix: effective_git_data_path() respects explicit paths with memory backend
- TestRelay: Added git_data_path() and archive config support for testing
- Integration tests for archive_read_only behavior
