feat(05-03): extend getProjectFullDetail + add offer assignment server actions

- Add offer_micros, project_offers imports to admin-queries.ts
- Add ProjectOfferWithMicro type to admin-queries.ts
- Extend ProjectFullDetail type with projectOffers + availableMicros fields
- Extend getProjectFullDetail() to query project offers and available micros in parallel
- Add z import and project_offers import to project-actions.ts
- Add assignOfferToProject, removeProjectOffer, updateProjectOfferTotal server actions
- All three actions call requireAdmin() and revalidate /admin/forecast
