Adds a streaming GET /ledger/export.jsonl route in ledgerRoutes.ts that emits canonical ledger entries in chunked JSON-Lines format, opening with a single-line manifest (params + estimated row count via a fast COUNT(*) query), injecting a # keepalive comment every 100 rows to keep proxies from dropping the socket, and using pg-cursor in batches of 100 for back-pressure with a _destroy handler that releases the DB client and cursor on early disconnect; emits export.stream.rows and export.stream.duration telemetry. Closes RevoraOrg#483
