feat(phase1b): sase.tr read-only connection

- prisma/sase/schema.prisma with User + UserSubscription (partial view)
- lib/db-sase.ts exports typed RO client
- /projects/sase shows live metrics (users count, new users 7d, active subs)
- seed marks sase as active

DATABASE_URL_SASE_RO wired to super_panel_reader (SELECT-only)
