fix(ha-bootstrap): register listener with iomgr epoll before election

Browse source 
vote_request_thread connects to peers via SSL. iomgr was started before
election but c->ep was only registered with epoll inside cluster_start(),
which runs after election. The TCP connect succeeded (kernel accepts it)
but SSL_accept was never called server-side, so SSL_connect failed
immediately — both vote threads went to deny in <1ms and ctrl-a could
never win a quorum.

Fix: add cluster_register_listener() that wires c->ep into iomgr's
epoll watch. Call it from myapp_run() right after iomgr_start/vtaskmgr_start,
before election. cluster_start() still calls iomgr_monitor again
(idempotent via EPOLL_CTL_MOD).
