Fix OpenAPI schema issues for API explorer

- Fix file schema to use 'file_name' instead of 'name' to match actual API responses
- Fix dictionary schema circular reference by using additionalProperties instead of properties
- Remove PATCH endpoints for test_data and migrations from spec (these don't exist in API)
- All schema definitions now match actual API responses
- YAML syntax is valid and spec loads without errors
