fix: Improve tray icon theming and installer icon handling (#44715)

Add "svgs" directory and icon files to installer, ensuring proper
install/uninstall and registry registration. Enhance logging in
general_settings.cpp for theme-adaptive tray icon config changes.
Refactor tray_icon.cpp to improve icon loading robustness, add detailed
diagnostics, and ensure fallback to default icon if theme-adaptive icon
fails to load. These changes improve error handling and maintainability
for tray icon theming.
