What this PR does:

A summary of relevant changes:

• Adds a status option "I am teaching homeschool with the BJC curriculum" to the status dropdown
• Iff the homeschool status option is selected, the teacher has the option to upload supporting files
• The teacher can upload additional supporting files by editing their profile
• The admin can both add and delete any teacher's supporting files

A future PR might add functionality to allow teachers to delete files that they uploaded by. This might be done by, for example, "marking" files to be purged when a teacher updates their profile from the edit teacher page.

Nope

Checklist:

• Has this been deployed to a staging environment or reviewed by a customer?
• Tag someone for code review (either a coach / team member)
• I have renamed the branch to match PivotTracker's suggested one (necessary for BlueJay) (e.g. michael/12345-add-new-feature Any branch name will do as long as the story ID is there. You can use git checkout -b [new-branch-name])
