live portrait port to new forge

with the new forge, this extensions says this... any thoughts how to fix it? I tried to install like 6 versions of pydantic but not luck.

All model fields require a type annotation; if flag_stitching_retargeting_input is not meant to be a field, you may be able to resolve this error by annotating it as a ClassVar or updating model_config['ignored_types'].

thanks in advance!

Start in extensions/sd-webui-live-portrait/scripts/api.py around live_portrait_api and LivePortraitImageRetargetingRequest, then reproduce the app_started_callback failure shown in the report. Determine the compatibility change needed for the installed Pydantic version; done means the extension loads without the reported PydanticUserError.
