Ports flomni's ffzp_in()/fosa_in() "skip the move (and, for the FZP,
the expensive feedback-disable + reset-enable cycle) if already there"
optimization to lamni's lfzp_in()/losa_in(). Also adds the same
skip-if-already-there check to losa_out(), which has no flomni
equivalent to mirror (fosa_out() always moves unconditionally there)
-- added as a lamni-side enhancement per discussion.
Checked every existing caller of lfzp_in()/loptics_in() before making
this change, since a skip changes behavior for callers that used to
get an unconditional reset. Found one real risk:
x_ray_eye_align.py's "Step 0: FZP centre" (the start of a fresh
alignment run) had its manual feedback disable/enable calls already
commented out, meaning it relied entirely on lfzp_in()'s old
unconditional reset to establish a correct interferometer zero.
flomni's equivalent call site doesn't have this problem because
flomni's alignment flow does its own explicit
feedback_enable_with_reset() independently beforehand -- lamni's
doesn't. Fixed by passing force_feedback_reset=True at that one call
site so it keeps its current always-reset behavior; no other lamni
caller needed this.
