[4.x] Prefer new Collection() over collect() helper

[ghabriel25]

Summary

This PR is a pure refactor that replaces calls to Laravel’s global collect() helper with direct instantiation of new Collection(...) throughout the Livewire 4.x codebase.

It aligns Livewire with a convention adopted in the Laravel framework itself, which prefers new Collection() for:

• Slightly better performance (one fewer function call)
• A shorter call stack
• Makes DX slightly better when navigating the framework
• Consistency across the framework internals

The change has no intended behavioral impact. All existing Collection method chaining, filtering, mapping, etc. continue to work exactly as before.

Motivation

The collect() helper is a thin convenience wrapper without any logic in it. Calling the helper adds an unnecessary extra stack frame and a global function lookup.

Laravel core has begun preferring the explicit constructor in its own source for the reasons listed above. This PR brings Livewire in line with that style.
