fix(controller): refuse replicated WAL writes before this boot's recovery (bug-1920) 
A restarted standby accepts the primary's connection during its startup
delay, before persist_recover runs. Catch-up entries written into the
un-recovered persist_t opened seg-...0001 with O_TRUNC and rewrote it,
and after recovery the stale fd kept filing new LSNs under that segment
name. The primary's filename-ordered streamer then skipped them, so a
standby needing that range never caught up and commits stalled.

persist_wal_write_replicated now returns -EBUSY until recovery completes
(the bug-1416 recovery_complete gate). ha_apply_wal_catchup_entry and
ha_handle_snapshot_chunk drop pre-recovery traffic without ACK or NACK.
Catch-up streams from min(NACK-derived join position, standby report),
and the streamer warns when a non-empty range yields no entries.
