fix(LamNI): ensure OSA is out before requesting the FZP-centre click

Both align() and find_rotation_center() moved the FZP in and immediately
asked the operator to click its centre, but only confirmed OSA was out
afterwards (via loptics_out(), which runs after that click). If OSA was
left in from a previous scan setup, it would still be in the beam path
during the FZP reference click. Add an explicit losa_out() call right
before lfzp_in() in both procedures; it's a cheap, skip-if-already-out
no-op otherwise.

Found while testing find_rotation_center() against the simulated LamNI.
