fix: microphone permission dialog hidden behind onboarding window

The app uses .accessory activation policy (no dock icon), which caused
the macOS microphone permission dialog to appear behind the onboarding
window. Users never saw the prompt, got auto-denied, and the "Settings"
button was a dead end since the app wasn't listed in System Settings.

- Add NSApp.activate() before AVCaptureDevice.requestAccess to ensure
  the system dialog appears in front
- Add "Try Again" button in denied state so users can re-trigger the
  permission prompt instead of being stuck
- Improve error message from "was denied" to actionable guidance

Bump version to 0.5.2.
