Editing your own permissions

[jlkravitz]

As a Board ED, I can edit my own permissions when reviewing users. This creates the odd scenario where I can remove compact-level admin privileges on my own account, which suddenly prevents me from editing my own (or other user) permissions on specific jurisdictions. Ideas include-

• Update API to limit scope of permission changes a user can make on themself
• Do not update API, but create frontend flow that communicates the implications of a self-permission change to the user
• Regardless, it may be helpful to visually highlight the current user in the users table (see screenshot).
