umvr_fsamy_tracked/umv_fsamy_tracked require feedback OFF but did not
enforce it. Add an _internal flag; for user/CLI calls, warn that feedback
must be off (active alignment may be lost), prompt (default yes), and
disable feedback on confirm. Internal callers pass _internal=True since
they already manage the feedback lifecycle (ftransfer_flomni_stage_out,
x_ray_eye_align height-centering and mvy jog).
