Enable subscription creation from customer dashboard without prior subscription

Feature request

Is your feature request related to a problem?

I would say no, rather convenience. So, customers who have never had a subscription cannot start one from the Polar customer dashboard.
This blocks a clean self-serve upgrade or purchase flow.

Describe the solution you'd like

Enable subscription creation directly from the customer dashboard, even when the customer has no previous or active subscription.

Expected behavior:

• Customer opens the dashboard
• Available plans are visible
• Customer selects a plan and completes checkout
• Polar creates and manages the subscription

This should work without requiring any existing subscription record.

Describe alternatives you've considered

Managing subscriptions to the new plan using the checkout API, redirect to Polar.
Which works btw.

Additional context

The goal is to treat Polar as the full source of truth for subscriptions, including first-time purchases, without custom billing logic.
