(Bug) Checkboxes cannot be sized down beyond a certain limit

[evadecker]

Description

When inserting or editing a checkbox field in the form creator, you cannot resize the checkbox smaller than a certain amount.

Steps to Reproduce

1. Go to the form creator
2. Upload a PDF.
3. Insert a checkbox field.
4. Try to resize the field to something small. Beyond a certain width the checkbox field will no longer resize.

Additionally, you can make non-square checkbox fields, which seems like it shouldn't be possible, and the "move" cursor is displays when hovering over the top/right/bottom/left handles. (Should be a resize-[direction] cursor)

I can take this one. I'll submit a minimal fix PR for checkbox/radio resize constraints and handle cursor behavior.
