feat(flomni): skip feye_out in tomo_alignment_scan when scan-ready

When the eye is already out, optics in, and feedback running, skip the
eye-out/optics-in transition to avoid an interferometer reset. Enables
repeated alignment scans and interleaving alignment into a tomogram
without leaving the current measurement position.
