[codex] Use Drizzle for PostgreSQL data access

[komagata]

Summary

• Add Drizzle ORM and a lazy PostgreSQL connection using DATABASE_URL.
• Add src/server/db schema definitions and src/server/services data-access functions for companies and docs.
• Move companies/docs data reads and writes away from Supabase table APIs while keeping Supabase Auth in place.
• Document the local Supabase PostgreSQL DATABASE_URL in .env.local.example.

Validation

• npm run lint (passes with existing warnings)
• npm run test:component -- --runInBand
• npm run build

Notes

Supabase is still used for authentication/session handling. Data access now treats Supabase as a PostgreSQL database through Drizzle.
