feat(ha-config-bootstrap): implement ha_wait_for_heartbeat_or_timeout (task 3.4)

Browse source 
- sem_timedwait on heartbeat_seen semaphore with CLOCK_REALTIME deadline
- deadline = now + election_timeout_ms + xorshift64 jitter
- Returns CTRL_STANDBY on heartbeat arrival (calls ha_do_demote)
- Returns CTRL_ELECTING on timeout (caller drives election)
- Allows OPCode_heartbeat through dispatch gate in CTRL_INIT state
- 3 new unit tests: standby-on-heartbeat, electing-on-timeout, gate-allows-heartbeat
- 24 Tests 0 Failures in test_ha_startup suite

- `sem_timedwait(&c->ha.heartbeat_seen, &deadline)` where `deadline = now + election_timeout_ms + xorshift64_jitter()`
- Heartbeat handler posts `heartbeat_seen` only when `ha.role == CTRL_INIT`; receiving a heartbeat transitions to `CTRL_STANDBY` and returns
- Election timeout fires → returns without setting standby; caller proceeds to `am_i_primary_quorum()`
