Propagate new fallback model to all remaining script references

All FALLBACK_${MY_ID}_COVERS_${REMOTE_ID}_TIER* references updated to
FALLBACK_${REMOTE_ID}_TIER* across fallback_test.sh, partnership_manager.sh,
docker_update.sh, mesh_monitor.sh, and monitor.php. mesh_monitor.sh drops
the inner covering-host loop — tier data now lives in the covered host's own
conf so no cross-host scan is needed. monitor.php reads from the covered
host's conf file rather than the local host's.
