The invite page showed "invalid or has expired, ask your admin for a new
invite" for any failed resolve call, including offline, timeouts and 5xx.
A member on a flaky connection was sent to their admin for a resend, which
revokes a token that was still valid.
Only the server's invalid_invite answer now ends on "Invite unavailable".
Any other failure shows "Couldn't load your invite" with a Try again
button that re-runs resolve, without a global error toast. Regression
tests cover a network rejection and a 500 followed by a successful retry.
