ACL Work - Create Group Page

[routerino]

Starting the task of making up a GUI for the ACL in anticipation of the API getting updated.

Starting work needed:

• New store and class to hold the ACL object
• Feature flag to hide/show relevant pages in the settings
• Group page that can add/delete users
• Searching and Sorting for group page

Research needed:

• Need to figure out how to create a selection menu in sveltekit that allows for searching, as a normal selection menu won't cut it after a certain size. could use something like svelecte, but given that I already have fuse.js searching I might just see if I can build one first.
