Feature: Connect page merges following + followers into one view
/connect combines who you follow (ap_following) and who follows you
(ap_followers) into a single list keyed by actor_uri, each with a direction
badge (following →, follower ←, mutual ↔) and, for accounts we deliver to, a
light 'last delivery' line. Failing/never-reached followers move into a
collapsed 'Unreachable' section at the bottom with the remove action, keeping
the main list clean. The two Following/Followers tabs collapse into one
'Connect' tab; the old routes redirect to /connect so links keep working.
i18n NL/EN/DE. Verified locally: merge/direction/unreachable logic + render.
