feat!: pagination

[faretek1]

It would be useful to be able to convert offset+limit into page numbers using the method of User.loves so that we can standardize the api. I recommend placing some function for this in commons.py

If we update some functions to use this instead of pages, it would be backwards incompatible. we could also add a handler that overrides the pagination calculation if you provide a page number manually

not sure if pagination is the correct word

list of operations to 'paginate' (i.e. ones that use page insetead of limit+offset)

• Classroom.student_names
• Classroom.class_studio_ids
• Classroom.activity
• Forum.posts
• (forum) get_topic_list
• User.loves (could be modified to use a shared function)
• sess.classroom_alerts
• sess.mystuff_projects
• sess.mystuff_studios
• ses.mystuff_classes
• sess.mystuff_ended_classes
• sess.connect_topic_list
• user.comments

this would break certain functions that use these as dependencies so care must be taken, e.g. get_comment_by_id

the logic can be extracted from user.loves
