What this PR does / why we need it:

The Feast UI currently serves the entire registry as a single serialized protobuf blob
via GET /registry. The frontend downloads this monolithic blob on every page load,
decodes it client-side, and extracts the slice it needs. This approach has two
fundamental problems:

  • RBAC is completely bypassed
  • Performance degrades with registry size

This PR replaces the protobuf blob approach entirely, making the REST API the only
data source for the Feast UI. feast ui now mounts the REST registry API at /api/v1 (via RegistryServer +
register_all_routes) and the frontend fetches data exclusively through these
endpoints.

Sorry, something went wrong.

Uh oh!
