Fix incorrect schema references in test feature file #41

Problem description

The test feature file code/Test_definitions/application-endpoint-registration.feature references two schema names that do not exist in the API specification:

1. Line 24 — registerApplicationEndpoints success scenario validates the response against /components/schemas/ApplicationEndpointsId, but the actual schema defined in the YAML is ApplicationEndpointListId.

2. Lines 33 and 43 — getAllRegisteredApplicationEndpoints and getApplicationEndpointsById success scenarios validate responses against /components/schemas/ApplicationEndpoints, but the actual schema defined in the YAML is ApplicationEndpointList.

These mismatches mean the schema validation steps in the feature file will fail or reference non-existent schemas.

Expected action

Update the feature file to use the correct schema names:

• /components/schemas/ApplicationEndpointsId → /components/schemas/ApplicationEndpointListId (line 24)
• /components/schemas/ApplicationEndpoints → /components/schemas/ApplicationEndpointList (lines 33 and 43)

Additional context

Correct schema names are defined in code/API_definitions/application-endpoint-registration.yaml:

• ApplicationEndpointListId at components/schemas
• ApplicationEndpointList at components/schemas
