Fix TypeError when Blade::getPath() returns null during view caching (#150)

* Fix TypeError when Blade::getPath() returns null during view caching

Allow the path parameter in FragmentAlias::encode() to be nullable and handle null paths by defaulting to an empty string. This prevents TypeError when caching views with Volt components where the path is not available.

* Fix PHPStan errors for Livewire internal classes

Add ignoreErrors for ComponentRegistry class references that are internal to Livewire and not available during static analysis.

* Register the layouts namespace for L4 compatible
