[Feature] - Configurabale aowow link

We should transform all hardcoded aowow links (from wowgaming) to be a configuration option for the user, so anyone is allowed to use their own aowow version without needing to change the code.

Edit:

This for aowow and wowhead reference links probably a toggle "use wowhead" or "use wowhead" or aowow as a fallback also.

Start by locating the hardcoded Aowow and Wowhead reference links in the PHP/WordPress project and then identify the existing configuration entry points. The work is done when users can select or configure their preferred link source, with the requested Aowow fallback behavior applied consistently.
