fix(bf): page-scoped CRO fixes on /odoo-black-friday/ (deal price, one deal buy, live countdown)

Fix 1: the On the Rise pricing card quoted $395 while the deal block said $295 first
year — a price contradiction within one scroll. On this page only the card now reads
$295.00 / 'for your first year, then $395 a year'. Other pages keep $395.
JSON-LD Offer price was already 295.00 and still matches the visible price.

Fix 2: the three list-price Buy Now buttons (data-id 6/4/5) competed with the deal.
Side Hustle and Powerhouse buy buttons removed on this page. The On the Rise card's
buy is now the deal purchase — the same one-click checkout as the offer block
(product 4, /coupon/HOST27?r=/shop/checkout), native POST so it works with JS off.
Tracking: the offer-block form is the single element carrying the Plausible Buy class;
the Bootcamp CTA and the two list-price buttons no longer carry it.

Fix 10: a time-remaining element near the offer and near the buy, computed client-side
from one documented constant (2026-11-30T23:59:59-05:00, US/Eastern). The static
sentence 'Ends Monday 30 November 2026.' still reads with JS off; past the instant the
text switches to the past tense. No visibility animation.
