iOS: Fix canvas touch events and auto-hide status bubble

- Disable scroll on WKWebView to allow touch events to reach canvas
- Add WKNavigationDelegate to intercept clawdis:// deep links from canvas
- Wire up onDeepLink callback to handle taps on canvas buttons
- Auto-hide status bubble after 3 seconds
