Trac ticket: #65819

What

Adds a dedicated PHPUnit class for rest_get_route_for_post(), covering route generation for posts, invalid posts, non-REST post types, and filter overrides.

Test-only; no production code changes.

Why

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

How

Add tests/phpunit/tests/rest-api/restGetRouteForPost.php with @covers ::rest_get_route_for_post.

• Returns /wp/v2/posts/{id} for a post
• Returns an empty string for an invalid post
• Returns an empty string when the post type is not show_in_rest
• Allows rest_route_for_post to replace the route

Testing Instructions

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