InstanceNotConnectedError and InstanceDisconnectedError now open the
ConnectInstanceModal instead of being swallowed silently. After the user
connects/reconnects, the friend request is retried automatically and a
success toast confirms both the connection and the sent request. All
other friend action errors (remove, cancel, accept, decline) now surface
as warning toasts instead of being silently discarded.
