/**
 * Video edit/delete execution scenarios.
 *
 * These tests go beyond the modal open/close tests in video-crud-flows.spec.ts
 * to verify the actual submission and deletion paths.
 *
 * Scenarios covered:
 * - SCN-edit-form-populated: Edit modal populates form fields from video data
 * - SCN-edit-field-unlock: Locked fields can be unlocked via "Edit field" button
 * - SCN-edit-title-submit: Editing title and submitting triggers edit-submit event
 * - SCN-edit-validation: Submit is blocked when title is empty
 * - SCN-edit-url-validation: Submit is blocked when URL is not HTTPS
 * - SCN-delete-confirm-executes: Clicking confirm delete dispatches deletion
 * - SCN-delete-modal-metadata: Delete modal shows video metadata
