fix: restore proper spinning animation for mobile refresh FAB

Reverted HTML replacement approach and restored the cleaner CSS-based
animation from commit 1855085.

Previous (wrong) approach:
- Replaced button HTML with spinner
- Modified both desktop and mobile buttons in apiClient.js
- Messy and inconsistent

Restored (correct) approach:
- Add/remove .spinning CSS class in click handler
- CSS animates only the icon inside the button
- Button itself stays unchanged
- Much cleaner implementation

Changes:
- Reverted apiClient.js changes from commit 9a49433
- Added .spinning CSS class and @keyframes rpg-spin
- Updated index.js click handler to bind both buttons
- Uses addClass/removeClass for clean animation control
- Includes drag detection to prevent accidental clicks

Now the mobile FAB icon spins smoothly when refreshing!
