feat: sort apps by recently-updated (#6875)

closes #6873 , see there for reasoning.

tested that on iOS already, works like a charm - and was much easier
than expected as @iequidoo already updated `timestamp_rcvd` on status
updates in https://github.com/chatmail/core/pull/5388

~~a test is missing, ordering is not tested at all, will check if that
is doable reasonably easy~~ EDIT: added a test
