Moved all variables over; moved git passthrough script to new location
and naming scheme; moved settings and mentions of gitea name; switched
ci woodpecker instance to use forgejo instead of gitea.
Admin deployment was very timing-dependent: If the server took a while
to set it up, it would always error out while deploying. This commit
adds sufficient grace-time into the admin request call before the error
occurs which should avoid it in most deployments (unless the server is
severely underpowered or over-taxed).
Also fixes admin creation to avoid root usage in the container when it
is not called for.
