For a reason, current wget versions error out when using localhost instead of 127.0.0.1 as the healthcheck for docker services. Probably has something to do with dns resolution - either on docker or wget end, but have not looked to deep into it.
Added healthcheck to gitea database contaier. Fixed initial admin setup checks - uses correct in-container user and fixed fail checks.
Added base gitea docker setup role. Adds automatic unattended setup with default admin account and optional email notification setup.
