Simplify config and add AdGuard DoH/DoT support

- Replace the hand-rolled Podman OCI container for Actual Budget with the
  native services.actual module (available in the pinned nixpkgs release);
  the container never actually had a backend enabled, so it likely never ran.
- Collapse cgit's Caddy routing to a single reverse proxy - the smart-HTTP
  git backend was already served on the same nginx vhost/port as cgit
  itself, so the separate /git/* -> 8085 route was dead and pointed at a
  port nothing listened on.
- Drop the unused kvm-intel kernel module from the guest hardware profile,
  and rename disko's misleadingly-named ESP partition (it's ext4, not a
  real EFI System Partition).
- Point common.nix's disabled autoUpgrade flake URL at this repo's own
  cgit hosting instead of a generic GitHub placeholder.
- Add AdGuard Home DNS-over-TLS (853) and DNS-over-HTTPS (8443) support,
  backed by an independent ACME certificate (modules/acme.nix) issued via
  a webroot Caddy serves on port 80.
