Let site admins have robust room management

[randysim]

Site admins should be able to

• kick out clubs
• reserve room for clubs
• update room settings (such as blocking them off on a certain day), etc.

Also, some more stuff to do with this

• in create meeting edge function, add checks to make sure you are booking a room on the right day in a valid time slot (there is no RLS afaik, only frontend checks). And if room is available for that day of week.
• in frontend, add checks for days the room is available. Right now there is only time check but we also need day of week checks.
• create a route to update room settings. Basically, when you block off certain days of a room, you must inform all clubs and admins of that club that their meeting on that day for that room is getting cancelled because the room is reserved.

As for reserving rooms, basically, the admin can select the organization, and FORCE assign a room to them (they can create an empty meeting called ROOM RESERVATION for an organization).

also when updating rooms, make sure to notify any organizations that their meeting is now invalid and deleted.
