feat(08-03): add query layer for offer phases and quotes

- Add getOfferPhases(microId) — get all phases for an offer micro
- Add getOfferPhaseServices(phaseId) — get all services assigned to a phase
- Add getQuoteById(quoteId) — get full quote header by ID
- Add getQuoteByToken(token) — get quote by public token
- Add getQuotesByClient(clientId) — get all quotes for a client
- Update imports to include new tables and types
- All queries properly typed with Drizzle ORM
- Build verified with npm run build
