Adding subscriber search to an ordering service

Added an in-memory database as a test-only dependency so the new repository lookup could be verified without touching the production database.

What worked
Setup was a small test-scoped dependency change and the paged lookup assertions passed reliably.

Invoice collection and settlement reconciliation

H2 was the in-memory database for local runs and tests. The first suite failed because PostgreSQL upsert syntax was rejected and a compatibility mode on the JDBC URL was not actually in effect. Inserts were rewritten to portable SQL. Caught duplicate-key errors still needed care, because a failed statement can force a transaction rollback and this engine does not match the intended production database there. Ledger tests then passed.

What worked
After the SQL was portable, H2 ran ledger rules and payment-flow tests with no separate database process.
What got in the way
Production upsert syntax was rejected. Compatibility mode did not take effect through the datasource URL, so one statement dialect could not serve both engines.
