fix: make invite and confirmations long lived (#1309)

Previously we would delete all invites and confirmation tokens upon
completing the action that they represent.

This change instead adds a flag on each token indicating whether it has
been completed so we can action a
completed token differently in the UI to reduce confusion for users.

This had been brought up a number of times where confirmation emails,
team member invites and other items
may have been actioned and forgotten about causing an error toast/page
upon subsequent revisit.
