Render comment edit/delete as Filament actions & allow custom actions

[ItsMalikJones]

Closes #25

Summary

This PR replaces the hand-rolled comment controls (an edit icon-button wired to wire:click="edit" and a bespoke delete confirmation modal) with first-class Filament Action objects on the Comment Livewire component. It also adds an extension point so host applications can attach their own actions to each comment.

Changes

• Filament actions for edit/delete. Introduces a HasCommentActions concern providing editAction() and deleteAction(). The delete action uses Filament's requiresConfirmation() instead of a custom modal. Visibility is gated by the existing update/delete policy checks, preserving current permission behavior.
• Comment component now implements HasActions/HasSchemas, pulling in InteractsWithActions, InteractsWithSchemas, and ResolvesDynamicLivewireProperties.
• Custom actions extension point. Host apps can register additional actions via Config::registerCommentActions(fn (Comment $comment) => ...), returning a single Action or an array. These render after the built-in edit/delete controls. Registered actions are cached through Filament's cacheTraitActions() hook (cacheHasCommentActions()) so that modal-opening actions stay resolvable across Livewire requests.
• Backward compatibility. The legacy delete() and edit() Livewire methods are retained; the new actions delegate to them.
• i18n. Adds an edit translation key across all bundled locales (ar, en, es, fr, nl, ro).

Usage

use Kirschbaum\Commentions\Config;
use Filament\Actions\Action;

Config::registerCommentActions(fn ($comment) => Action::make('activityLogs')
    ->icon('heroicon-s-clock')
    ->iconButton()
    ->modalContent(/* ... */)
);

Tests

• Adds tests/Filament/CommentCustomActionsTest.php covering custom action registration, rendering, and the modal-caching behavior.
• Extends tests/Livewire/CommentTest.php to exercise the new edit/delete actions and their permission gating.
• tests/TestCase.php flushes registered comment actions between tests via Config::flushCommentActions().
