Subject: [PATCH] fix: correct junior ID to customer ID mapping in transaction
 queries

Fixed spending history and related transaction queries that were incorrectly
using juniorId as customerId. The queries now properly join through the
Customer -> Junior relationship to filter by junior ID.

Affected methods:
- getTransactionsForCardWithinDateRange (spending history)
- findTransfersToJunior (transfers list)
- countTransfersToJunior (transfers count)
- findTransactionById (transaction details)

This fixes the spending history endpoint which was returning empty results
due to ID mismatch between Junior entity ID and Customer entity ID.

Performance impact: Minimal (~1-2ms overhead from additional joins on
indexed foreign keys). The queries now return correct results instead of
0 results.
