fix(omny): increase laser tracker on-target wait timeout, add status print

Bump max_repeat from 25 to 100 (~12.5s to ~50s) in
laser_tracker_wait_on_target, since the tracker was timing out too
early during beamtime. Print a status message once the retry-enable
branch kicks in so it's visible the wait is still in progress.
