Subject: [PATCH] Fix WordPress manager 500: define DB_HOST, lazy-load MySQL
 provDb
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Core.php: add DB_HOST constant (was undefined, causing fatal error on any
  WordPress manager page load in PHP 8)
- WordPressManager: make provDb lazy (only connects to MySQL when actually
  needed for install/clone/delete — not on list/info which only use SQLite)
