fix(ui): reliable federation-join feedback (90s timeout + re-check + success)

Browse Source 
Joining a Fedimint federation is heavy and routinely outlasts the default 15s
client timeout while still succeeding server-side, so the UI wrongly showed
failure. Bump the join timeout to 90s, and on any error re-check the list: if a
new federation appeared the join worked — show 'Federation joined.' instead of
a misleading error.
