fix(mobile): improve refresh button - float over all tabs, add animation, fix focus

**Changes:**
1. Move button to float over all tabs (not just Stats)
   - Removed from userStats.js HTML
   - Added to template.html as floating absolute element
   - Now visible on Status, Info, and Inventory tabs

2. Fix sticky black focus state
   - Added :focus { outline: none } to CSS
   - Call blur() after click to clear focus immediately

3. Add refresh animation
   - Button spins during updateRPGData() call
   - Smooth 0.8s rotation with @keyframes
   - Uses .spinning class added/removed in JS

4. Improve theming and positioning
   - Positioned absolute top-right (10px, 10px)
   - Increased to 44px for better touch target
   - z-index: 100 to float above content
   - Already uses theme colors (--rpg-highlight, --rpg-text)

Mobile UX now:
✅ Button visible on all tabs (floating)
✅ Spins smoothly when refreshing
✅ No sticky black state after tap
✅ Properly themed across all themes
