Restores the newer local gitea-values.sops.yaml (2026-03-27) over the
upstream scaffold (2026-03-10). Adds database, cache, session, and queue
sections pointing to external PostgreSQL/Valkey (S3 platform services),
and disables bundled postgresql/redis/valkey sub-charts.
Also adds .sops.yaml encryption policy for railiance-apps.
