Migrate frontend from MongoDB/Firebase to Odoo 19 backend

- Remove all MongoDB and Firebase dependencies
- Add Odoo proxy layer (src/lib/odoo.ts) for JWT-authenticated API forwarding
- Rewrite auth routes (login, logout, register, reset) to use Odoo endpoints
- Add catch-all API route ([...path].ts) to proxy remaining endpoints to Odoo
- Rewrite special-case routes for file uploads and binary responses
- Delete ~85 legacy API routes now handled by catch-all proxy
- Replace *.be.ts MongoDB utilities with stub implementations for SSR compat
- Update Dockerfile: remove MONGODB_URI, switch from yarn to npm
- Update session.ts to store Odoo JWT token
