V109 QUICK FF WIDTH-ONLY FINAL ADJUSTMENT

Base
- Built from V108.

Fixes
- In Quick finite-fault placement mode, comma/period no longer call the old stamp_adjust_width_keep_aspect() function.
- This means ,/. now change only patch width. They no longer also stretch/shrink patch length.
- J/K remain the only patch-length controls.
- The Excel-style grid row spacing now uses one common layout width based on the C3/origin dip, so rows do not shear or squash when individual cells have different dips.
- Individual patches still use their own dip-projected width for their actual rectangle and for local depth/height calculations.
