🐛 Fix composite primary with AfterValidator/Annotated

[patrick91]

The title is currently a lie :D but there's a test for what's broken, and I think it's because the FieldInfo we get in get_column_from_field is the Pydantic one and not the SQLModel one

EDIT: I guess this is not just about primary keys, but it's about any custom attribute used in SQLModel's Field :)

I have also being working on solving this and will make a PR solving the issue with the associated tests. I will link it here when its done.
It might be a bug on pydantic side like they had in v2.0.0 and corrected in v2.0.1
For now i suggest to fix the version pydantic~=2.11.10 that works just fine since it have not updated pydantic-core to support python3.14.

Inspired by your test - added a fix here: https://github.com/fastapi/sqlmodel/pull/1607/files

@vimota hi Victor! thanks for that, I think it's probably best to wait for @tiangolo to check how to fix this ;)

Sounds good - didn't realize he was on it!

For what it's worth, I do think this is exactly what the Pydantic metadata field is for.

@patrick91 @vimota
Check the PR me and @YuriiMotov linked to this issue.
The problem is not due to resolution of metadata but Pydantic re-associating the values if FieldInfo.
To the the get column method is being passed as a parameter the value of a pydantic.FieldInfo and not a sqlmodel.FieldInfo.

Closing this one in favor of #1603 and #1607, which both now contain the tests of this PR - we'll just have to pick one of the two to merge.
