fix(ha-bootstrap): priority staggering and candidate_id in election

Two Raft correctness fixes:

1. Priority staggering in ha_wait_for_heartbeat_or_timeout():
   Add my_priority × election_priority_step_ms to the timeout so
   ctrl-a (priority=0) times out first and starts election before
   ctrl-b (priority=1) and ctrl-c (priority=2). This gives the
   highest-priority node a head start and prevents simultaneous
   campaigning that causes perpetual split votes.

2. candidate_id in vote RPC:
   Pass the actual node name (myconf->name) as candidate_id instead
   of "". This fixes the voted_for deduplication gate (Req 2.6):
   a peer that already voted for ctrl-a will correctly deny a
   second vote request from ctrl-b in the same term.

   Thread context gets my_name field; am_i_primary_quorum() takes
   my_name parameter; all call sites updated (myapp.c, ha.c RDHUP,
   test_ha_election.c stubs).

feat(ha-config-bootstrap): implement vote handlers and term persistence (task 4.2)

- ha_persist_term(): atomic write+rename of ha_term_file_t with CRC32
- handle_request_vote(): term/voted_for/freshness/catch-up gate chain
- handle_request_vote_reply(): vote counting, quorum+all-replied signaling
- ha_elect_evaluate_and_signal(): quorum+yield+zero-config gates (4.3 early)
- am_i_primary_quorum(): single-node shortcircuit + 2-round retry (4.3 partial)
- 24 Tests 0 Failures in test_ha_election suite

test(ha-config-bootstrap): RED phase tests for quorum election logic (task 4.1)

- 21 test functions covering all 12 acceptance criteria (req 2.1-2.12)
- Tests: 2/3 quorum wins, 1/3 loses, voted_for enforcement, freshness gate,
  single-node self-elects, split-vote retry, in_catch_up denial, jitter
- Build fails with undefined reference to handle_request_vote,
  ha_elect_evaluate_and_signal, am_i_primary_quorum (expected RED proof)
