fix(controller): cold start elects in ~1.7 s, not ~10 s; ctrlstatus appliedLsn on the primary (bug-1879, bug-1878) 
bug-1879: on a fresh HA cluster the config-holding ctrl-1 started its
term-1 election before its peers ran; connect failures count as "no"
votes (bug-1423), so it lost at once and became a follower with no
leader. ctrl-2/ctrl-3 hold no config and are voters only (by design),
so nothing retried until ctrl-1's 10 s standby liveness timeout: every
cold start had no primary for ~10 s.
- ha_note_leaderless() marks a config-holding node that becomes a
  follower with no leader known; the liveness poll then retries the
  election (PreVote) after HA_LEADERLESS_RETRY_MS = 1 s, doubling up to
  heartbeat_timeout_ms. Primary contact or becoming leader clears it.
- ha_heartbeat_is_fresh() answers "no" while leaderless: last_activity
  then only holds the watchdog's arm time, and the failover gates took
  it for a live primary.
Live cold start: primary 1.7 s after the first node started (was ~10 s).

bug-1878: ctrlstatus_fill() reported ha->applied_lsn for every role, a
standby-only counter a primary never advances, so every primary showed
"appliedLsn: 0". A primary now reports persist->last_applied_lsn. The
controller-status design doc's "already correct in every role" note is
corrected.

Tests: 5 new in test_ha_failover_prevote.c, 1 new in test_ctrlstatus.c
(RED: expected 4900, was 0); controller suite 1256/0. HA soaks:
sequential 6 rounds PASS, chaotic 6 rounds PASS (zero divergence, zero
job loss).
