Initial Setup:
1. Add the portal flake input to Webserver-Infra/flake.nix with a Forgejo access token.
- Does this need to be in just the inputs, or the outputs as well? I'm still very much learning nix and these things get confusing.
2. Add services.portal.enable = true; to Webserver-Infra/configuration.nix
3. Remove the existing users.users.portal and groups because they exist in this flake now
4. Clone the repo on the server, place the .env, build, then run nixos-rebuild switch. This is mainly to start the service, I presume. The build is just so that the service has something to
 start.

To update:
1. git pull
2. Apply shell-instance environment variables for placeholder values to then run `npm ci && npm run build && npm ci --omit=dev`
3. Restart the systemctl service (portal.service) to pickup the changes because the service is in charge of the `node build` command.
