klopez4212 6b5bb6f5a3 feat(mobile): refresh onboarding and smooth QR scanner motion (#8019) ...

## Summary
Refresh mobile onboarding with light/dark gradients, an animated fuzzy
Buzz wordmark and tagline, and bottom-aligned glass/ghost actions.
Remove the dot grid and idle scroll bounce, and smooth the QR scanner's
continuous corners and spring transitions by deferring camera teardown
until dismissal finishes.

### Related issue
N/A — no matching mobile onboarding issue or PR found.

### Testing
- Mobile formatting, analysis, and full test suite passed at
`0bb357f7a`.
- Regression coverage includes shader animation/reduced motion, keyboard
reachability, scanner interruption, deferred camera disposal, and
rendered error contrast in both themes (mutation-checked).
- Signed iOS release build installed on iPhone Air; Kenneth tried the
onboarding and scanner during iteration and approved the final blur.
- Agent review completed with no correctness blockers. Android device
validation was not performed; hosted checks run separately.
