Force automatic WireGuard key regeneration if the rotation interval has passed

[jordan-ivpn]

Bug report

A customer reports:

I am the user that reported the key rotation on wireguard a while back for the desktop app on MacOS. I noticed that the iPhone app doesn't auto-renew if it's been on airplane mode overnight and then I take it off in the morning. Sometimes I have to manually regenerate the keys because the expiration date is past due but it doesn't notice so the keys don't renew and the internet doesn't work until I manually regenerate.

You fixed the desktop app and it is working really well now, but it is only the iPhone app

We are not able to reproduce the issue so far. Note that when the WireGuard VPN tunnel is connected, the app will check every 1h if keys need to be rotated, so it is not immediate.
