[Feature Request] macOS menu bar improvements: make icon semi-transparent when VPN is not active & right-click to toggle status

Now icon is always white. Other VPN apps (like Tunneblick on the screenshot) usually make icon semi-transparent when VPN is not active

Suggestion 1: make icon semi-transparent (something like 30% like other apps) when no profile is active in the sing-box.

Suggestion 2: make use of right mouse click to toggle active profile (turn off when it's on and turn on when it's off) It's really cool when apps utilize high speed and make repeating actions like this in one click instead of two. If we start to show active status in the menu bar icon, this mouse shortcut would be very useful It's not a common practice, but good for power users, especially if you add a description about this feature Example where this is made is Flow app (green timer on the screenshot)
