(Git-4) Refactor rerender in auto_tick module

[ytausch]

Description:

This PR continues the git-backend-related changes and refactors the auto_tick logic to reduce the complexity of the rerender code.

Note: This PR removes a migrators directory from a check for trivial rerender changes. We discussed this here: #2812 (comment).

Since the broken check did not cause any issues, I did NOT add .ci_support/migrations instead.

Checklist:

• Pydantic model updated or no update needed

Cross-refs, links to issues, etc:

Please merge #2948 first.

Sorry for the delay on write access! You should have permissions now!

Thank you!

I need to look at the rest but I did notice one thing right away.

There is an inconsistent mix of passing arguments by keyword and in one case passing a keyword as an arg. Let's try and clean that up.
