Optimized the Customer Feedback Form for mobile devices and responsiveness. Key improvements: - **Enhanced Touch Targets**: Increased padding and size for buttons, form inputs, and rating stars (min 44px tap targets where applicable) to improve usability on touchscreens. - **Responsive Layout**: - Stats cards now stack gracefully and use more compact typography on small screens. - Header layout adjusts from a row to a column on mobile, with full-width filter buttons for easier access. - The feedback list now handles long text and metadata better on narrow screens with improved truncation and spacing. - **Mobile-First Design**: - Added `touch-action: manipulation` to prevent accidental zooming. - Improved form sticky behavior (only sticky on desktop). - Reordered sections on mobile to prioritize recent activity while keeping the form easily accessible. - **Visual Refinements**: Added custom scrollbar styling and improved empty state visuals for a more polished mobile feel. - **Accessibility**: Added `aria-label` to icon-only buttons and ensured proper label-input associations.
