[Feature]: Prevent Superusers from removing their own supeuser permission

[swift2512]

Snipe-IT Version

How can we help?

There could be a safety mechanism that prevents removing superuser permission from the last person who has it and from your own account.
I've logged in with my only superuser account and set permission it to Inherit (leaving everything else on Inherit) because system said ' This user has at least one individual permission set, which may override group permissions.'

The only way to get your crown back - through direct DB manipulation. If you have no access to DB tools - getting back could take some time and leave system unmanaged for that period (API scheduled tasks would fail because user now has no permissions to performs these).
