Forgejo's runner defaults to fetching `uses: org/repo@vN` from its
instance's mirror (data.forgejo.org), which doesn't host most
GitHub-marketplace actions like cachix/install-nix-action. Pointing
default_actions_url at github.com makes the existing workflow Just Work
without fully-qualified URLs in `uses:` lines.

The gitea-actions-runner module loads tokenFile as a systemd
EnvironmentFile, so it needs KEY=value lines, not a raw token. Comment
updated to match — the runner failed to start the first time around
because the file just contained the bare registration token.

Adds services/forgejo-runner.nix as a host-gated module on the mediaserver
and switches the flake-update workflow from runs-on: ubuntu-latest to the
self-hosted fred-nix label, mapped to catthehacker/ubuntu:act-latest for
GitHub-action compatibility. Token lives at /var/secrets/forgejo-runner-token
so it stays out of the Nix store.
Also drops the stray result/ build symlink from the worktree.
