Subject: [PATCH] feat(billing): brand checkout + auto-prefill user details
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#1 Checkout branding (within Razorpay's hosted-UI limits):
- image: /icons/192.png — Tia logo in the checkout header
- theme color #fb7185 (Tia rose, matches app theme-color) — was terracotta
- Note: Razorpay Checkout is their hosted UI; logo + brand color + name are
  the only customisable bits. Fonts/layout cannot be changed (platform limit).

#2 Auto-prefill name/email/phone:
- UpgradeButton now fetches /api/auth/profile on mount and passes
  prefill {name, email, contact} to Razorpay. User can still edit in checkout.
- Saves manual entry; uses the phone we now collect.

(#3 "seller doesn't support recurring payments" is a Razorpay ACCOUNT setting,
 not code — needs subscriptions enabled on the account. Handled separately.)
