Jamil 6413a45589 fix(apple): Explicitly check if system extension is installed (#7691) ...

In #7680, I stated that a VPN profile's status goes to `.invalid` when
its associated system extension is yanked. That's not always true. I
observed cases where the profile was still in the `.disconnected` state
with the system extension disabled or removed.

So, now we explicitly check on startup for two distinct states:

- whether the system extension is installed
- whether the VPN profile is valid

Based on this, we show an improved GrantVPNView for macOS only with
clear steps the user must perform to get set up.

If the user accidentally closes this window, they can open the Menubar
and click "Allow VPN permission to sign in" which will both (re)install
the extension and allow the profile.
