feat(ha-repl-hardening): standby snapshot receive handler (task 3.5c)

Browse source 
ha_handle_snapshot_chunk writes chunks to snap.part, on isLast verifies
total_size, atomic renames to snap-{lsn}.bin, loads via new
persist_load_snapshot wrapper, sets applied_lsn=checkpoint_lsn.
3 tests: 2-chunk assembly, size mismatch, null args. Wired into
myreq_handler OPCode_snapshotTransfer dispatch.
