Subject: [PATCH] fix(critical): remove @abstractmethod from video
 character/edit/extension methods

Convert all 8 new video methods from @abstractmethod to concrete implementations
that raise NotImplementedError. This prevents breaking external third-party
BaseVideoConfig subclasses at import time.

Methods affected:
- transform_video_create_character_request/response
- transform_video_get_character_request/response
- transform_video_edit_request/response
- transform_video_extension_request/response

External integrators can now upgrade without instantiation errors; NotImplementedError
is only raised when operations are actually called on unsupported providers.

This restores backward compatibility with the project's policy.
