feat(workplan): RAIL-PL-WP-0001 S3 Platform Services Baseline
First workplan for railiance-platform (S3). Separates platform
services from the S2 cluster runtime layer per ADR-003:
- T01: standalone PostgreSQL HA Helm chart (platform namespace)
- T02: migrate Gitea to external DB, remove subchart coupling
- T03: relocate Gitea Helm values to railiance-apps (S5)
- T04: smoke + HA failover tests (D3 policy)
- T05: relocate railiance-backup tool from S2 to S3
- T06: standalone Valkey deployment (enables Zulip reuse)
