Pull request overview

This PR enhances the “custom scanner” workflow by introducing edit and delete capabilities, improving dialogs, and updating related strings so users can manage saved custom scanners more directly from the scanner browser UI.

Changes:

• Add edit + delete actions for saved custom scanners (including a deletion confirmation dialog).
• Extend dialogs to support “new vs edit” behavior and reuse deletion dialog with custom title/text.
• Update/extend localized string resources (EN/DE/IT) for the new UI.
