Generate 1254 Catppuccin Mocha themed placeholder SVGs covering every
icon referenced in FreeCAD's .qrc resource files that did not already
have a kindred-icons override.
Each placeholder uses:
- The standard 32x32 viewBox with #313244 surface0 background
- A dashed border in the workbench accent color (e.g. yellow for
Sketcher, blue for PartDesign, peach for BIM/Draft/Arch, etc.)
- An abbreviated label so the icon is identifiable at a glance
This brings total kindred-icons coverage from 190 to 1444 icons,
ensuring every FreeCAD icon resolves to a Catppuccin-themed version.
