feat(frontend): make Give Feedback button translucent with glassmorphism effect

Apply frosted glass (glassmorphism) styling to the Give Feedback and Tutorial
floating buttons so users can see text content underneath them.

Changes:
- Reduce background opacity from 1.0 to 0.55 (rgba(65,65,64,0.55))
- Add backdrop-blur-md for frosted glass blur effect
- Add subtle white border (border-white/10) for depth
- Add shadow-lg for elevation

Both the Give Feedback and Tutorial buttons are updated consistently.
