Add scroll-to prop to pagination component

[joshhanley]

The Scenario

When using Flux's pagination component, clicking a pagination button changes the page but doesn't scroll the user back to the top. This is a common expectation — especially on long lists where the pagination controls sit at the bottom of the page — and is something Livewire's own pagination views support out of the box.

<?php

use App\Models\User;
use Livewire\Attributes\Computed;
use Livewire\Component;
use Livewire\WithPagination;

new class extends Component {
    use WithPagination;

    #[Computed]
    public function users()
    {
        return User::query()->paginate(10);
    }
}; ?>

<div>
    <flux:table :paginate="$this->users">
        <flux:table.columns>
            <flux:table.column>Name</flux:table.column>
            <flux:table.column>Email</flux:table.column>
        </flux:table.columns>

        <flux:table.rows>
            @foreach ($this->users as $user)
                <flux:table.row :key="$user->id">
                    <flux:table.cell>{{ $user->name }}</flux:table.cell>
                    <flux:table.cell>{{ $user->email }}</flux:table.cell>
                </flux:table.row>
            @endforeach
        </flux:table.rows>
    </flux:table>
</div>

The Problem

The <flux:pagination> component had no scroll behaviour implementation. Livewire's pagination views include a scrollIntoView() call on each button via x-on:click, but Flux's pagination component didn't have an equivalent.

The Solution

Added an opt-in scroll-to prop to the <flux:pagination> component, matching the approach used by Livewire's pagination views. When enabled, clicking a pagination button triggers a scrollIntoView() call on the target element.

The prop is opt-in (disabled by default) and accepts either a boolean or a CSS selector:

{{-- Scroll to body (default target) --}}
<flux:pagination :paginator="$users" scroll-to />

{{-- Scroll to a specific element --}}
<flux:pagination :paginator="$users" scroll-to="#table" />

When using the table component, the prop can be forwarded using the pagination: prefix:

<flux:table :paginate="$users" pagination:scroll-to />

The table component now uses Flux::attributesAfter('pagination:', ...) to forward any pagination:-prefixed attributes to the underlying <flux:pagination> component, making it extensible for future pagination props.

Note: There is a known issue in Laravel where multi-word kebab-case attributes (like scroll-to) don't get converted to their camelCase prop equivalents (like $scrollTo) when forwarded via :attributes. To work around this, the pagination component uses Flux::forwardedAttributes() before @props to manually handle the conversion — the same pattern used by the with-field component.
