IRIS PROMPT STUDIO V2.6.27 — HAND SURFACE LABELS & MENU CLEANUP

- Hand surface regions now display only the accurate surface: right/left palm in palm mode, right/left back of hand in dorsal mode.
- Hand surface labels are corrected in tooltips, region selection, selected-card chips, precision coordinates, and generated prompts without changing region IDs.
- Removed obsolete patch-version wording from newer clothing catalog entries.
- Confirmed menu and section version badges are absent from the current UI; centralized patch history remains in changelog.html.
- Updated assets' query-string revision to prevent older cached scripts/styles from showing outdated labels.
- Preserved stored IDs, JSON import/export, and original image assets.
