console: store models, proto, and SQL migrations are misaligned

### 🐛 Describe the bug

The console BFF has three sources of truth for its persisted entities:

1. Proto — apps/console/api/proto/console/v1/console.proto
2. GORM models — apps/console/api/store/models/*.go
3. SQL migrations — apps/console/api/store/migrations/001_initial.sql

This issue tracks the alignment work. Nothing here is a feature request — it's strictly about making the existing three layers say the same thing.

### Steps to Reproduce
