Removed the Windows-specific forced Adwaita icon theme override from win32_configure_icon_theme(), so ZoiteChat will no longer switch to Adwaita at runtime and can use the app’s own icon assets from the configured icon search path.

Removed Adwaita icon bundle copy rules from the Windows packaging project (copy.vcxproj), so share/icons/Adwaita is no longer pulled into Windows build artifacts.
Removed Adwaita icon inclusion from the Windows installer manifest (zoitechat.iss.tt), so installer builds no longer ship Adwaita icon files.
