System tray icon should adapt to the current system theme

The application's system tray icon should automatically adapt to the current system theme.

Currently, the tray icon uses a fixed color, which can make it difficult to see depending on whether the user is using a light or dark theme.

Expected behavior:

• Use a black tray icon when the system is using a light theme.
• Use a white tray icon when the system is using a dark theme.
• Ideally, the icon should update automatically whenever the system theme changes.

This would improve visibility and provide a more consistent native desktop experience.

Good advice, I'll try to implement whenever I have some free time.
