trustedcoin: add option tor.proxy

Browse Source 
By disabling `trustedcoin.tor.proxy` and enabling `clightning.tor.proxy`,
`trustedcoin` can be used without Tor proxying, while clighting still
uses Tor for lightning layer connections.

Previously, disabling Tor for `trustedcoin` required to also disable
Tor for clightning.

Also fix the workaround in the docs for the trustedcoin Tor connection issues:
The previous config snippet only affected systemd hardening settings,
but didn't disable Tor for trustedcoin.

If you face these issues and you still need to use trustedcoin, use can disable
clightning's tor hardening by setting this option in your `configuration.nix`
file:
```
services.clightning.tor.enforce = false;
To work around this and connect via clearnet instead, set this option:
```nix
services.clightning.plugins.trustedcoin.tor.proxy = false;
```
