Implemented a complete client-side workflow for creating, applying, and displaying visual signature overlays on the PDF canvas. - Added "Unterschreiben" buttons with modern styling (purple gradient, hover effects) to apply signatures. - Introduced a signature creation popup (DxPopup) with Draw, Text, and Image tabs, including validation for required fields (Name, Place). - Rendered German-style signature overlays with image, separator line, and text (Name, Position, Place, Date in dd.MM.yyyy format). - Ensured automatic re-rendering of overlays on page load, zoom, and page changes. - Added `escapeHtml()` for XSS protection of user-provided text. - Styled popup, canvas, and buttons with a modern, clean design. - Suggested future enhancements for server-side stamping or integration with commercial PDF libraries.
