fix(coupon A/B): discount banner never displayed + same-day expiry killed the test

Browse source 
Two bugs that invalidated the price A/B/C test (20/30/0):

1. OrderPriceBanner.astro shipped with data-api="" (PUBLIC_API_URL was never
   set at build), so the ?code= discount lookup hit a relative /api/... path on
   the static host -> 502. The struck-through discounted price NEVER rendered
   for anyone who clicked a coupon link; every visitor saw full price. Fixed to
   fall back to window.__PW_API (set in Base.astro) then the prod API host, the
   same pattern the rest of the site uses.

2. Daily coupons expired 23:59 ET of the SEND day. The builder runs in the
   morning ET and carriers read mail across ~36h, so most discount arms saw an
   already-expired code by open time. Extended to 23:59 ET of the day AFTER
   send (~1.5 days), and updated the email + banner wording to match.

Net: the A/B/C arms can now actually be redeemed, so the test can produce a
real signal. Measured by paid Stripe orders keyed to the arm (re-hash of the
converter email), not bot-polluted opens/clicks.
