feat(05-01): append five offer tables + Drizzle relations to schema.ts

- Add primaryKey to drizzle-orm/pg-core import
- Define offer_macros, offer_micros, offer_services, offer_micro_services, project_offers
- Add Drizzle relations for all five new tables (+ projectOffers in projectsRelations)
- Export TypeScript infer types for all new tables
