Disable posts likes and edits for hidden posts without permission

[rafalp]

It doesn't make sense to be able to like/unlike or edit hidden posts.

Permissions to check:

• check_see_thread_post_permission
• check_see_private_thread_post_permission

To fix, override get_thread_post method on a view accessing post:

class ThreadPostSomethingView:
    def get_thread_post(
        self, request: HttpRequest, thread: Thread, post_id: int
    ) -> Post:
        post = super().get_thread_post(request, thread, post_id)
        check_see_thread_post_permission(
            request.user_permissions, post.category, post.thread, post
        )
        return post
