refactor: change add student to add resident, change url length

[CK-7vn]

Description of the change

This increases the allowed length of the URL for helpful_links, after some research I have found that the most common character count for URL's is between 80-100 characters long, given that the actual url is not displayed and the user explicitly names the url. In the database we limit the URL to 255 characters so the URL character limit has been updated to be 255 characters. Secondly, the "Add Students" button has been changed to "Add Residents" and in the form.

Helpful Link URL -> Description field is the URL for character count length reference

@CK-7vn Did you mean to make changes to this file? It re-introduces the problem with clicking on Edit User, pressing Esc, and then clicking a different Edit User but seeing data from the first click.

See issue #638

Just have a question on this with regards to the EditUserForm. Rest of the code looks fine.
