refactor(divi): DiviTab geht im Reiter „Compatibility“ auf

Der eigene Divi-Reiter entfällt. DiviAdminExtras behält Admin-Hinweis, Orphan-Bereinigung vor der Ausgabe (lit_mcp_compat_profile_load), Hinweis zum nächsten Schritt und zur privaten Testseite (lit_mcp_compat_profile_intro), Zustandstexte mit Quelle (lit_mcp_compat_explanation), Automatik-Notiz und Visual-Builder-Hinweis (lit_mcp_compat_profile_extra) sowie die Spalten Quelle, Probleme und Betroffene Tools über die neue, gegen fehlerhafte Callbacks abgesicherte Erweiterung lit_mcp_compat_capability_columns. Texte, Doku, CSS (lit-mcp-compat-*) und Smoke auf den neuen Reiter umgestellt, tote divi_*-Hinweise entfernt.
