Fix: Remove @pure directive from file input component

The @pure directive causes Blade compilation errors when used with
Livewire Blaze due to the component containing dynamic translation
helpers ({!! __() !!}) and PHP conditionals.

Error: 'Cannot end a section without first starting one'

This component cannot be safely optimized at compile-time because:
1. It uses translation helpers that need runtime evaluation
2. It contains PHP conditionals (if/else) for multiple file selection
3. The dynamic wire:model attribute binding requires runtime context

Removing @pure allows the component to render correctly while still
maintaining full functionality.
