/**
 * ====================================================================================
 *  Aether V3 Nested CRUD API Integration Tests
 * ====================================================================================
 *
 *  Purpose:
 *  This test suite verifies that the SvelteKit frontend correctly uses the
 *  nested API endpoints for creating, updating, and deleting child objects.
 *  It builds on the patterns established in `v3_api_security.test.ts`.
 *
 *  Key Scenarios Verified:
 *  1.  **Nested Create:** Confirms that creating a child object (e.g., an Event Location)
 *      sends a POST request to the correct nested URL (`/v3/crud/:parent_type/:parent_id/:child_type`).
 *  2.  **Nested Update:** Confirms that updating a child object sends a PATCH
 *      request to the correct nested URL.
 *  3.  **Nested Delete:** Confirms that deleting a child object sends a DELETE
 *      request to the correct nested URL.
 *
 *  Strategy:
 *  -   Uses the same API mocking and state injection strategy as the security tests.
 *  -   Focuses assertions on the outgoing request's URL, method, and payload to
 *      validate the refactored data-handling logic.
