Breaks our Plaid sync process out into more manageable classes. Notably, this moves the sync process to a distinct, 2-step flow: 1. Import stage - we first make API calls and import Plaid data to "mirror" tables 2. Processing stage - read the raw data, apply business rules, build internal domain models and sync balances This provides several benefits: - Plaid syncs can now be "replayed" without fetching API data again - Mirror tables provide better audit and debugging capabilities - Eliminates the "all or nothing" sync behavior that is currently in place, which is brittle
