What

Trac ticket: #65819

Makes the data providers in tests/phpunit/tests/filters.php static.

Why

PHPUnit data providers should be static so they do not depend on test instance state and remain compatible with current PHPUnit usage in Core.

How

• Convert data_priority_callback_order_with_integers() to public static
• Convert data_priority_callback_order_with_unhappy_path_nonintegers() to public static

Test-only; no production code changes.

Testing Instructions

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