Allow remote code repo names to contain "."

[Rocketknight1]

Thanks to @not-lain for spotting this one! When the repo path for a remote code model contains ., our code fails to import it correctly because . is interpreted by the Python import machinery as a module separator.

For now, we monkey-patch this in get_class_in_module, but we can consider a more thorough overhaul of the import machinery if problems crop up elsewhere.

TODO:

• Test this with custom cache dirs
• Add a test for this somewhere?

Fixes #28919

Very nice fix IMO! Let's be extra careful as this is trust remote code zone!
