security: enable full systemd-status for group 'proc'
Previously, systemd-status was broken for all users except root.

Use a 'default' deny policy, which is overridden for group 'proc'.

Add operator to group 'proc'.

Also, remove redundant XML boilerplate.

security: simplify and fix dbus configuration
Previously, due to the dependency on a helper service, this dbus config
was initially inactive after system boot, allowing for unrestricted use
of the problematic dbus call.
This also broke the accompanying VM test on faster systems.

Remove 'allow' policy for root because it's a no-op:
1. It's overridden by the 'mandatory' deny policy.
2. Root can use all dbus calls anyways, regardless of policy settings.

Also, add some comments.

rename dbus.nix -> security.nix
This file has a broader scope than just configuring dbus.

clightning: add announce-tor
From the clightning manpage:

autolisten=BOOL By default, we bind (and maybe announce) on IPv4 and
IPv6 interfaces if no addr, bind-addr or  announce-addr options  are
specified. Setting this to false disables that.

We already set bind-addr by default, so autolisten had no effect.
Therefore, this commit replaces autolisten with the more granular
announce-addr option.

For now we are Tor-only, so we only need to announce our hidden service
to accept incoming connections. In the future, we can add clearnet
connectivity with `addr` and route connections into our netns with NAT.
