Automated pricing dataset publisher

A scheduled job now builds and publishes a structured pricing dataset, keeping downstream consumers in sync with the latest provider prices.

A new write client and scheduled publishing pipeline ship pricing data to a structured dataset on a regular cadence.

A cron-triggered endpoint builds the current pricing dataset and publishes it automatically

A staff-only endpoint allows on-demand dataset pushes outside the scheduled window

The integration layer gained a typed write client for the dataset host, with full test coverage
