feat: improve delivery modal UI for mobile and WeCom sidebar

- Increased modal dimensions (500px width, 85vh height) with responsive breakpoints for mobile devices
- Enhanced form controls with larger fonts (14-15px), better padding, and improved touch targets
- Added scrollable template options with max-height constraint and visual polish (shadows, backgrounds)
