chore(db): re-export quota modules in localDb (B/F2)

Adds re-export blocks for quotaPools (7 functions), quotaConsumption
(4 functions with gcQuotaConsumption alias), and providerPlans (4
functions with getProviderPlan/listProviderPlans/etc. aliases).
Zero logic added to localDb.ts — Hard Rule #2 maintained.
