Describe the Bug

For example, when a book's description is empty, editing and saving it will result in HTML tags being appended to the empty field. As a result, an empty <p> tag is rendered in the description.

Quick Fix

app/Entities/Models/HasHtmlDescription.php

/**
 * Check if the entity has a meaningful description (not just empty HTML tags).
 */
public function hasDescription(): bool
{
    $cleanedHtml = str_replace(['<p>', '</p>', '<br>', '<br/>', "\xC2", "\xA0", " "], '', $this->descriptionHtml());
    return !empty(trim($cleanedHtml));
}

• resources/views/books/show.blade.php
• resources/views/chapters/show.blade.php
• resources/views/shelves/show.blade.php

@if($book->hasDescription())
    <div class="text-muted break-text">{!! $book->descriptionHtml() !!}</div>
@endif

Steps to Reproduce

1. Go to https://demo.bookstackapp.com/books/bookstack-demo-site
2. Click Edit on the right side.
3. Remove description content and save.
4. Click Edit again and save, it will add an empty line(<p>).

Expected Behaviour

• No empty line.
• Trim empty description.
