gsp-phys: relay verify hardening and counter exposure (default off)

- the work_relay state line now reports the real backend data-compare
  verify_fail plus a verify_transient count, distinct from the sema-service
  hold re-read verify_fail (previously the backend counter was dropped)
- a relayed copy whose host-side compare fails is re-read and re-compared
  once after a short delay; a transient mismatch counts as success and only
  a persistent mismatch falls back to the software apply as before
- the final-mismatch diagnostic now logs the semaphore target/payload/poll
  time, the first differing byte and 16-byte dumps of live dst, live src and
  a submit-time analysis material, flagging source mutation vs snapshot/dst
- the fault no_event path logs the post reason/return
All changes are behind the default-off relay path.
