feat: Allow forcing a refresh of the comments list

[luisdalmolin]

Closes #105.

Problem

There was no way to reload <livewire:commentions.comments> immediately after saving the record. Custom getComments() items (e.g. activity-log status changes) only appeared after the next poll.

Fix

Listen for a public commentions:refresh Livewire event:

• CommentList reloads its computed comments
• Comments forwards the event as comment:saved so targeting the parent component still refreshes the nested list

protected function afterSave(): void
{
    $this->dispatch('commentions:refresh');
}

Tests

• Comment list shows comments created after the initial render once commentions:refresh is dispatched
• Comments component forwards commentions:refresh as comment:saved

Full suite: 182 passed. Pint clean. PHPStan unchanged — the 7 pre-existing errors in tests/Livewire/CommentReactionTest.php are also present on main.
