Fix/transaction inconsitensies (#190)

* fix: request explicit page size from Enable Banking API to fetch all transactions

The API defaults to ~10 transactions per page when no limit is specified,
causing incomplete syncs for users with more transactions.


* fix: enhance DELETE operations and add missing RLS policies for multi-tenant support
