fix: Correct HA roadmap status to in-progress (waiting for Oracle/Patroni)

- Changed status from 'complete' to 'in-progress'
- Removed premature 'completed' date (Nov 25 was DNS failover only)
- Updated description: Waiting for Oracle Cloud free tier approval
- Item breakdown:
  * ✅ DNS failover working (app-level HA)
  * ✅ Health monitoring operational
  * ✅ Live test validated (0s downtime)
  * ⏳ Oracle Cloud approval pending (database-level HA)
  * ⏳ Patroni 3-node cluster planned (true PostgreSQL HA)
  * ⏳ Automatic DB failover with Patroni
  * ⏳ Distributed consensus with etcd
- Current: App HA working, Database HA in progress
