Add Blade fallback for delegate components

[ganyicz]

The scenario

A user has Blaze installed and uses a custom Flux icon or variant:

<flux:icon name="custom" />

Where "custom" is a Blade view in resources/views/flux/icon/custom.blade.php without a @blaze directive.

The problem

The icon component uses flux::delegate-component and Blaze assumes all delegate targets are optimized.

But the custom icon template doesn't have @blaze, therefore it's not compiled into a function.

Resulting in an exception:

Call to undefined function _eab27ebdf4ee954a9a05ceed5425e512()

The solution

Instead of forcing all custom components to be blaze-compiled (livewire/flux#2411), we check at runtime whether the delegate target is a Blaze component. If not, we skip Blaze entirely and fall back to standard Blade rendering.

Custom components without @blaze just work — no configuration needed, no forced compilation.

Replaces livewire/flux#2411.
