feat: Added list method functionality to API

[lukeskywalker22]

Implemented list method to list all timetables from database

def list(self, **filters: typing.Any) -> "list[campus.model.TimetableMetadata]":
        """List timetables matching the provided filters.

        Args:
            **filters: Arbitrary filter parameters applied to the query.

        Returns:
            list[campus.model.TimetableMetadata]: Matching timetable metadata objects.
        """
        resp = self.client.get(self.make_path(), query=filters if filters else None)
        resp.raise_for_status()
        return [
            campus.model.TimetableMetadata.from_resource(item)
            for item in resp.json()
        ]

The tests don't do anything useful, only mock the API schema which is unnecessary: we control the API on both ends (server and client)

Remove the gitignore change and the test and should be good to merge
