Trac ticket: #65819

What

Adds a dedicated PHPUnit class for rest_get_route_for_post_type_items(), covering collection routes, invalid post types, non-REST types, custom namespace/base, and filter overrides.

Test-only; no production code changes.

Why

rest_get_route_for_post_type_items() had no direct @covers coverage. Small helper coverage fits the #65819 test cleanup track.

How

Add tests/phpunit/tests/rest-api/restGetRouteForPostTypeItems.php with @covers ::rest_get_route_for_post_type_items.

• Returns /wp/v2/posts for the post type
• Returns an empty string for an invalid post type
• Returns an empty string when the post type is not show_in_rest
• Uses custom rest_namespace and rest_base when registered
• Allows rest_route_for_post_type_items to replace the route

Testing Instructions

1. npm run test:php -- --filter Tests_REST_API_RestGetRouteForPostTypeItems
2. npm run test:php -- --filter Tests_REST_API_RestGetRouteForPostTypeItems -c tests/phpunit/multisite.xml
3. npm run test:php -- --filter Tests_REST_API_RestGetRouteForPostTypeItems --order-by=random
4. npm run test:php -- --group restapi

Please remove the local tear_down() override. Parent set_up() already calls reset_post_types() before each core test, and this class has no earlier fixture consumer. Keep the new collection guard/filter checks.
