Self-Service Stripe Customer Billing Portal Integration¶

Implemented self-service billing portal integration enabling tenants to manage their payment methods, invoices, and billing info:

1. Backend Endpoint

• Implemented `POST /api/v1/superadmin/tenant-billing/customer-portal`:
  - Validates tenant company ID and retrieves Stripe Customer ID.
  - Creates a Stripe Billing Portal session with dynamic `return_url`.
  - Securely returns session URL to the client.

2. Frontend Integration (CompanyProfile.tsx)

• Connected `Update Payment Method` button in top notice banners for `past_due` accounts.
• Added `Manage in Stripe` triggers with loading state indicators.
• Cleaned up redundant button duplicates across the Company Profile view to provide a clean, single-action user experience.

3. Verification

• Verified portal URL generation and return flow on localhost.
• Verified that updating payment method in portal resolves failed payment retries.
