ksmithandClaude Sonnet 5 d42bf114dd Drop accepted/revoked invites from the pending invites list (#61)
list_site_invites returned every invite ever sent, so the admin UI's
"Pending invites" section kept showing accepted/revoked rows forever
(just relabeled with a status badge) instead of dropping them. Filter
the query to pending only, and have the revoke action remove its row
from local state immediately instead of leaving a relabeled one behind.
