Fix macOS window not appearing when switching Spaces

[kdroidFilter]

Summary

• Fixes window not appearing when clicking tray icon after switching to a different Space (desktop) on macOS
• Window now intelligently detects if it has focus before deciding to hide or bring to front
• When window is on a different Space (unfocused), it's brought to the current Space instead of being hidden

Problem

When the tray window was visible on Space 1 and the user switched to Space 2, clicking the tray icon would attempt to hide the window (because it was marked as "visible") rather than bringing it to the current Space. This resulted in the window not appearing at all when clicking the tray icon from a different Space.

Solution

Before hiding the window on a tray icon click, check if the window has focus:

• If focused: hide the window (normal toggle behavior)
• If not focused: bring window to current Space using setMoveToActiveSpace() and toFront()

Test plan

• Open the tray window on Space 1
• Switch to Space 2 using Mission Control or keyboard shortcut
• Click the tray icon from Space 2
• Window should appear on Space 2 (not hide)
• Click tray icon again
• Window should hide normally
