Add subscription metadata to Co-Pilot

🔍 Problem Statement

Currently, clients don’t have a way to export subscription metadata from the platform.

💡 User Story

As a business owner, I want to export and query subscription metadata so that I can analyze and extract specific subscription details based on key/value pairs.

🎯 Definition of Done (DoD)

✔️ Subscription metadata is supported in Co-Pilot.
✔️ Platform users can extract subscription information based on metadata key/value pairs.
✔️ Platform users can:
   • Export all subscriptions that have a specific metadata key/value.
   • List all metadata associated with a given subscription.
