Get unique metadata keys from topics across all topics in the organization.

Backward compatibility behavior:
- Pre-v2026_03_13 clients: Uses strongly consistent reads
- v2026_03_13+ clients: Uses eventually consistent reads
- Override: Send X-Roboto-Connection-Consistency header to explicitly control behavior

This endpoint uses eventual consistency for improved performance and scalability.
Results may not immediately reflect very recent writes. If you've just created or
updated topic metadata and don't see it in the results, retry after a brief delay.

### Access control
 - requires_resource_owner
 - Restricted tokens need the API scope `api.everything_else`
