[MM-13671] Rework Team InviteId Creation and Updates (#10536)

* Add regenerate invite ID endpoint; Dont allow inviteID updates via other methods; Remove unrequired checks in get handler

* Fix tests; Dont accept TeamId as invite ID

* Ensure all teams have an InviteID set

* Custom Selector to get empty teams; dont crash when inviteid set fails

* Remote InviteId from TeamPatch

* Add missing translation

* Translation string order

* Use sync store

* gofmt
