Compatibility with Pydantic 2.10

[Viicos]

Due to a circular import, the AnyComponent alias is imported in an if TYPE_CHECKING: block in fastui.components.forms:

FastUI/src/python-fastui/fastui/components/forms.py

Lines 12 to 13 in 5d9d604

	if _t.TYPE_CHECKING:
	from . import AnyComponent

and later used in one of the defined models for this module:

FastUI/src/python-fastui/fastui/components/forms.py

Lines 187 to 191 in 5d9d604

	loading: '_t.Union[_t.List[AnyComponent], None]' = None
	"""Components to display while the form is submitting."""
	footer: '_t.Union[_t.List[AnyComponent], None]' = None
	"""Components to display in the form footer."""

While this used to work in <2.10 because of namespace pollution inconsistencies, it doesn't with 2.10 as AnyComponent (which doesn't exist in the module namespace at runtime) isn't available.

Best way forward would be to fix the circular import, haven't found a viable implementation yet.

I think the easiest solution would be to clean up the contents of the __init__.py into separate files and have the AnyComponent also separate

The example code in the docs is also broken because of pydantic 2.10. Downgrading to 2.9.2 makes it work again

I have managed to not throw any errors but its not rendering anything anymore will try to figure out a nice solution

Finished the refactor and have working version of FastUI added a PR so maybe we can get someone from pydantic to look at it in near future.
