Fix ListField Double-Touch Issues and Improve Order Comment Dialog

[No0ne558]

Summary

This PR fixes critical double-touch triggering bugs in form zones and begins improvements to the Order Comment dialog keyboard interface.

Changes

1. Fixed ListField Double-Touch and Click Area Issues

• Problem: Touchscreen inputs were triggering field actions twice due to both Touch and Mouse events calling FormZone::Touch()
• Solution: Changed ListFormZone::Touch() and ListFormZone::Mouse() to call LayoutZone::Touch() instead, which only updates coordinates without triggering field actions
• Click Area Fix: Corrected ListField offset calculation from label_width + .6 to label_width + 1 and boundary from entry_width + 1 to entry_width to match visual button boundaries
• Impact: Tender Settings and all form zones with list fields now respond correctly to single clicks/taps without double-triggering

2. Order Comment Dialog Improvements (Work in Progress)

• Redesigned dialog with modern 6-row QWERTY keyboard layout (removed overlapping keyboard layers)
• Implemented visible text entry box at top of dialog with absolute positioning
• Fixed text display updates - typed characters now appear in RED as user types
• Added proper background clearing to prevent text artifacting when clearing input
• Adjusted text positioning for better vertical centering in entry box
• Status: Text entry box is functional and visible. Still polishing final implementation.
