test(12-02): add comprehensive tests for per-property resolution

- Create SharedClassEmbeddable fixture (class-level Shared with Empty override)
- Create EmptyClassEmbeddable fixture (class-level Empty with Shared override)
- Create ConflictClassEmbeddable fixture (both class-level attributes)
- Test mixed Shared/Empty properties with AddressWithEmptyAndSharedProperty
- Test class-level Shared with property override to Empty
- Test class-level Empty with property override to Shared
- Test class-level conflict throws ValidationException
- Test plain embeddable resets all to defaults
- Test resolution chain logging with debug level
- Test property override logging message
