Andrey's clutter rule: calibration force-rerun = erase the file, not a
config checkbox. pose_recalc removed everywhere (field/dialog/properties/
copy; old configs' leftover key is ignored harmlessly), poseSequencePass
lost its allow_recalc parameter. Every file-gated reuse now prints the
delete-to-recalculate hint:
- TILE-CALIB: 'reusing ... delete <name>-POSE-RT-TILE-CALIB.tiff to recalculate'
- RT-STATE dc_center: 'delete <name>-RT-STATE.json (or its dc_center field)'
- FPN (CorrectionFPN): 'reusing saved <name>-FPN.tiff - delete it to
  recalculate (verify Rotation period first - a mismatch bakes an
  azimuth-sector content ghost into the FPN)'
