Windows Updates
New Print Preview window by @mghe01 in #255
PicView-print-dark-theme-4.0

In multi-user Remote Desktop environments, the Windows Desktop Experience feature is unavailable, preventing access to the built-in "Print Pictures" dialog when using the 'print' process verb. As a result, printing defaults directly to the user's default printer without allowing printer selection.

Added Enhanced printing functionality by adding print preview with support for selecting printers and print properties.
Added grayscale conversion and Avalonia to GDI bitmap rendering
Ensured 1:1 accuracy between on-screen preview and physical/PDF output
