Added - Option to disable HTML5 validations and enable custom error messages - Conditional visibility for error message fields (only shown when custom messages are enabled) Fixed - Fixed `ArgumentCountError` in `DateRangeConstraintValidator::__construct()` by implementing `ContainerInjectionInterface` with proper dependency injection - Removed invalid `#[Autowire]` attribute that was causing constructor injection issues Technical Details - When "Enable custom error messages" is checked, the form's HTML5 validation is disabled via `novalidate` attribute - Server-side validation remains enforced for all required fields
