fix(faker): resolve infinite loop and ensure non-empty responses
- Fix infinite loop in SchemaFaker by directly dispatching to specific fakers after resolution - Ensure ObjectFaker always returns at least one property even if none are required - Restore lost unit test cases in NumberFakerTest and SchemaFakerTest - Add FakerBugFixCest acceptance test to verify path parameter injection and non-empty responses - Apply PHPStan fixes for iterable types using best practices
