feat(import-fifa17): seed unopenedPackIds as Core entitlements

Carry unopenedPackIds through the importer: Profile model -> Report ->
ApplyPlan. GenericImportRequest now emits entitlements[] (one definition_id
per unopened pack instance, order+duplicates preserved), which Core's import
seeds as unconsumed packs rows in the same transaction. Closes the economy
import gap so a migrated profile's unopened packs become Core entitlements
(feeding purchasegroup/credits/userMassInfo). Idempotency unchanged (import
fingerprint). +1 test; 26 pass, clippy -D warnings clean.
