## Problem
After migrating webhooks and API keys from workspace to core level, REST
API endpoints were still creating entities in workspace schema
(`workspace_*`) instead of core schema, causing webhooks to not fire.
## Solution
- Added dedicated REST controllers for webhooks (`/rest/webhooks`) and
API keys (`/rest/apiKeys`)
- Updated dynamic controller to block workspace-gated entities from
being processed
- Fixed OpenAPI documentation to exclude these endpoints from playground
- Ensured return formats match GraphQL resolvers exactly
## Testing
✅ All endpoints tested with provided auth token - webhooks and API keys
now correctly stored in `core` schema
