Task: update the VideoPress onboarding dialog to use the new plugin's pricing table screen.

Benefits:
- This would help to promote the paid plan for new users.
- Keeps the experience consistent.
- Provides an ability/link for users to enter a license key.

Note: the dialog is visible through My Jetpack -> VideoPress

Start in My Jetpack's VideoPress onboarding dialog and compare its current flow with the linked Figma design. Confirm that the dialog uses the new plugin pricing table screen and exposes the license-key entry link; verify the flow from My Jetpack → VideoPress.
