feat: game templates, schemas and validator

Public game templates for GBR Hosting, one games/<id>/game.yaml per game,
imported from the panel. A Go tool validates them against JSON Schemas and
checks for credentials, private addresses and consents that default to
accepted; CI runs it on every push.

Admin/RCON passwords are no longer shared defaults: they are blank with
x-generate so the panel creates one per server, and Palworld/ARK no longer
publish their RCON/REST ports.
