bug: inconsistent modal focus management and ARIA roles

[nanaf6203-bit]

Summary

PageTransition.tsx modal wrappers do not trap focus, do not restore focus on close, and have inconsistent ARIA roles across modal types.

Affected area

• src/components/PageTransition.tsx
• src/components/ui/dialog.tsx
• Modals: WalletModal, TransactionProgress, TransactionDetailsModal, TransactionConfirmation, etc.

Steps to reproduce / impact

Keyboard users get trapped or, conversely, exit the modal without focus returning. Inconsistent ARIA roles means screen readers intermittently ignore the dialog.

Expected behaviour

Adopt a single <Dialog> primitive (Radix UI is already a dependency) for every modal. Disable body scroll, trap focus, return focus on close, expose aria-modal and aria-labelledby.

Acceptance criteria

• Replace ad-hoc modal markup with Radix Dialog across the app.
• Add Playwright test asserting focus is trapped and restored.
• axe-core has zero modal violations.
