Enhance system tray/menu bar

[rupokghosh]

Summary

This enables the system tray/menu bar icon to appear on macOS when Whispering starts, providing quick access to
recording controls and app actions directly from the menu bar.

The menu structure provides essential actions organized with separators: recording controls at the top, window management options, settings access, and quit. Left-clicking the tray icon shows the menu, giving users immediate access to all features without needing to open the main window.

How does this PR work with #868?

• There seems to be some overlap in the UX and code.

• There seems to be some overlap in the UX and code.

This one is more lean and just adds some basic functionalities that I thought could be useful immediately, if we can get the other one reviewed and merged, we can close this one without merging. Thoughts?
