Subject: [PATCH] Fix: Dirty-state marker ("*") not shown for edited system
 printer presets (#11900)

Fix missing dirty marker for edited system printer presets

System printer presets did not display the modified (“*”) marker in the sidebar when edited. Unlike other preset types, printer presets use `printer_model` as their display label, bypassing the normal dirty-state formatting.

This patch prepends the modified suffix to the displayed name when the selected system printer preset is dirty, restoring consistent UI behavior across all preset types.
