Fix detector daemon status check and dumpsys-hang stale status

action.sh: use short pgrep patterns so the enforcement/detector 'running'
check resolves correctly instead of falsely reporting 'not running'.
cgdetect.sh: wrap dumpsys telephony.registry in timeout so a blocking
registry read can no longer freeze the status file and stall the frame
counter.
