fix(ha): wire raft trace to DEBUG3; drop NOP on promoted ep; fix --vcpus in deploy script

- ha.c: add raft_cb_trace callback wired to s_real_cbs.on_trace; emits
  RAFT[pN] term=T event=E at DEBUG3 level, visible with -vvv flag.
- ha.c: repl_ack_decode_and_dispatch now silently drops OPCode_nop and
  OPCode_reply instead of WARNING — heartbeat NOP replies from standbys
  arrive on promoted endpoints and are expected.
- deploy-ha.sh: fix --vcpu -> --vcpus; add \$VERBOSE passthrough so
  start.sh respects VERBOSE=-vvv from the environment.
