refactor(webkit): address Copilot PR review comments

Address all 7 Copilot review comments from PR #3:

1. Remove deprecated `onPopup` field - unused, replaced by `onPopupCreate`
2. Remove unused `NewWebViewWithRelated` function - popups use `NewBareRelatedWebView`
3. Implement print functionality - `ShowPrintDialog()` now calls `webkit.NewPrintOperation()`
4. Fix WebView ID injection - use number instead of string to eliminate any theoretical injection concern
5. Use JSON marshaling for keyboard shortcuts - prevents potential script injection

All changes maintain backward compatibility:
- JavaScript already handles webview ID as `string | number`
- JSON marshaling produces valid JavaScript string literals
- Print function is bound to Ctrl+Shift+P and actively used
