Phase 3: Package layer overhaul — fix critical bugs + proto enhancement

Proto (package.proto):
- Add 11 new Package fields to Create/Update/Get/GetAll messages
- Add 8 new fields to CustomerPackageModel for frontend

Critical Bug Fixes:
- VerifyGoldenPackagePurchase: Replace hardcoded ×2 with package.DiscountMultiplier from DB

Query Fixes:
- GetAllPackageByFilter: Add IsDeleted filter (was returning soft-deleted packages)
- GetCustomerPackages: Apply IsDeleted+IncludeInactive filters, sort by SortOrder, return new fields
- GetCustomerPackageDetails: Load PackageFeatures from DB (was hardcoded), add IsDeleted filter, return new fields
- GetCustomerPurchaseHistory: Include Transaction (was null → ReferenceCode always empty)

UpdatePackage: Add 12 new fields (SortOrder, IsActive, IsBasePackage, etc.)

Build: 0 errors
