OTGS Installer

This release makes site-key activation and plugin recommendations more reliable, fixes the Add Themes tab, adds missing translations, and includes a security update.

• Fixed a fatal error on admin screens on PHP 8.4 caused by an incorrectly declared parameter.
• Added a clear message when your site key has been deleted, instead of the confusing "Development Site" banner.

Plugin recommendations and Add Themes
