Release v0.0.0.20

New setting "Outlook-Sicherheitsabfrage automatisch erlauben"
sets registry keys under HKCU\Policies\Microsoft\Office\16.0\
Outlook\Security to auto-approve Object Model Guard prompts.

Applied at app startup and when saving settings. Disabling the
option removes the registry values (back to Outlook default).
Works with all Outlook versions (2016-2024, same registry path).
No admin rights needed (HKCU).

Outlook must be restarted after changing this setting.
