Release v1.3.0: String Escape & UI tweaks

Add changelog entry for v1.3.0 and introduce String Escape/Unescape feature. Improve JSON formatter UX (double-click selects value, right-click copies selection, auto word wrap/no horizontal scroll). Clear input after generating QR/Barcode and optimize shortcut creation, working directory and window style settings. Update README and README_ZH to mention the new Escape feature and add EscapePage.xaml to the project file lists.
