Fix examples and SDK for Immich v2 API compatibility

- Fix AssetUploadStatus serialization to use snake_case (created/duplicate/rejected)
- Fix AssetOrder serialization to use lowercase (asc/desc)
- Add file_created_at/file_modified_at to UploadAssetBuilder
- Fix AddAssetsBuilder response type to Vec<Value> instead of AlbumResponse
- Fix ServerAbout model - version is String not ServerVersion struct
- Update upload_photos.rs to handle duplicate responses correctly
- Update server_info.rs to display new ServerAbout fields
- Update AGENTS.md with new example list
