Improve signature handling and navigation stability

Browse Source 
Updated button logic to display "Unterschreiben" only when signature fields exist. Changed `_signaturePopupVisible` to always be `false` for consistent popup behavior. Improved navigation after caching a signature by nullifying `_report`, adding a delay for UI updates, and using `forceLoad: true` for clean circuit teardown. These changes enhance user experience and prevent potential crashes.
