Billing Change

Change an existing subscriber's tier in-app (no portal round-trip).

Called via fetch from the plans page, so it returns JSON (not a redirect). Switches the tier within the SAME billing interval via the Polar merchant API (proration applied immediately); switching monthly<->annual stays in the portal. Uncancels first if the sub was scheduled to cancel.
