Developer TODO Checklist:

• Okta Integration: Fetch active user session information (first/last name, email, avatar).
• Stripe Portal Integration: Link the "Billing & Subscriptions" button to your Stripe Customer Portal URL to allow self-serve cancellations, renewals, and invoice downloads.
• Provide profile update forms: Implement inputs to change password or edit user details, sync updates back to Okta user meta.
