fix(federation): compute relay targets before member deletion in leave handler

getGroupDmTargetOrigins() was called after the leaving user's dm_members row
was deleted, causing their instance to be excluded from member_remove and
ownership_transfer relay fan-out if they were the only member from that peer.
Move the target origins and leaving user lookups to before the deletion.
