Using django-lifecycle hooks results in `error: Untyped decorator makes function "x" untyped [misc]`

When using the @hook decorator from django-lifecycle on a model method, mypy throws the following error:

error: Untyped decorator makes function "x" untyped [misc]

This means that, currently, all methods decorated with @hook(...) are annotated with # type: ignore[misc]. The goal of this issue is to remove those type: ignore[misc] comments, while still having mypy pass its validation. Depending on the fix, it may be necessary to split the work up into multiple PRs as there are a lot of instances of this across the codebase.
