Change JumpIn component behavior

[braianj]

The current behavior of the JumpIn component in UI2 (src/components/JumpIn/JumpIn.tsx) is to display a modal when the launcher is not installed:

if (!hasLauncher) {
  setIsModalOpen(true)
}

Problem

Showing the modal in this case is not the expected behavior and results in an inconsistent user experience compared to the landing.

Expected behavior

The component should not open a modal when the launcher is missing.
Instead, it should receive a new property isSignedIn and change its behavior accordingly:

if (isSignedIn) {
  window.open(downloadUrl, '_self')
} else {
  window.open(onboardingUrl, '_self')
}

Proposed changes

• Add a new prop to JumpIn called isSignedIn.
• Remove the modal logic tied to !hasLauncher.
• Implement the conditional flow based on isSignedIn:
  • If true, redirect to downloadUrl.
  • If false, redirect to onboardingUrl.

Expected outcome

The JumpIn component will no longer show a modal when the launcher is not present.
Instead, it will handle the user flow directly based on the isSignedIn property, ensuring consistency across dapps.
