fix(controller-status): ctrlstatus_fill must prefer a live registry slot over a stale disconnected one (task 8.6, bug-1819) 
Found live during task 8.5's optional catching-up-observation attempt:
a killed-then-reconnected standby can end up occupying a NEW
replicator_t.standbys[] slot while its OLD slot (host/port still
populated, ep == NULL) also matches the same configured peer.
ctrlstatus_fill's primary-side peer-status loop stopped at the first
host:port match, so it permanently reported that peer dead even
minutes after it had genuinely reconnected and fully caught up --
violating Requirement 13.3's "true, currently-known connection status"
guarantee.

Fix: scan all MAX_STANDBYS slots for a given peer and prefer any slot
with ep != NULL over a slot with ep == NULL; fall back to dead only
when no matching slot is live. Read-only, lock scope unchanged from
task 8.2.

TDD RED->GREEN (1216 Tests: 2 Failures -> 0), independently reproduced
by the reviewer (exact RED replay) plus two independent live
kill/backlog/restart/poll cycles on separate fresh clusters, both
confirming the previously-stuck standby now converges to ok.

design.md's Locked Decision 3 corrected to document the fix.
