DataManager & Digitizer: Dialog Improvements and Mobile Optimization

This PR implements comprehensive improvements to the DataManager and Digitizer dialogs, focusing on usability, mobile responsiveness, and enhanced configuration options.

Dialog System Modernization

• Migrate to Mapbender.Popup: Complete migration from jQuery UI dialogs to Mapbender.Popup for better integration
• Code modernization: Convert ES5 pseudo-classes to ES6 classes (DialogFactory, FormRenderer, FormUtil, TableRenderer, FeatureEditor, FeatureRenderer, FeatureStyleEditor, StyleAdapter, ContextMenu, Toolset)
• File structure: Rename files to start with uppercase letters for consistency

Dialog Configuration Enhancements

• Dynamic popup titles: Support data expressions in popup titles (e.g., data.title + " - " + data.ort)
• Template literal syntax: Add support for ${data.property} syntax in expressions
• Remove close button: Hide redundant close/cancel button in edit dialogs (X button in title bar remains)

Form Item Improvements

• Label type enhancements: Add title attribute support for type: label
• Dynamic expressions: Enable expression evaluation for title, label and text types (similar to existing html type)
  • Supports JavaScript expressions: "'Titel lautet: ' + data.title"
  • Supports template literals: "${data.title}"
  • Supports complex expressions with functions: "(function(){ return data.gemarkung ? 'Gemarkung: ' + data.gemarkung : 'Gemarkung:'; })()"
• Image preview layout: Display image preview below the title instead of next to it for better mobile experience

Display-Only Mode Detection

• Automatic Save button hiding: Hide Save button when form contains only display fields (no editable inputs)
• Visual feedback: Show magnifying glass icon instead of pencil in table rows for display-only forms
• Smart detection: Automatically detect editable vs. display-only fields

Mobile Optimization

• Responsive dialogs: On mobile devices (max-width: 767px):
  • Dialogs take full viewport width
  • Limited to upper portion of screen (max 60vh)
  • Content area scrollable for long forms
• Improved usability: Better touch-friendly interface on mobile devices
