feat(bf): put the HOST27 deal on the homepage; deal window now starts 2 November

The coupon applies today (signed-out test: post_basket -> /coupon/HOST27 ->
cart 295.00 from a 395.00 list), so the offer starts today, not on 16 November.

- index.html: one seasonal banner above the hero, a single <a> to
  /odoo-black-friday/. Homepage components and CI only (midnight/brass/cream,
  Marcellus/Inter). No script, no tracking tag, no event: the homepage has no
  consent gate, so nothing measurable may be added there. Hero, server
  selector, section order and JSON-LD untouched. Dated for removal after
  30 November 2026.
- odoo-black-friday/: every start claim 16 -> 2 (meta, og:image:alt, JSON-LD
  WebPage description + two FAQ answers, hero-sub, two body FAQ answers).
  End date, countdown instant, forms, consent gate and the three conversions
  unchanged.
- odoo-hosting-offers/: same start claim on the second ad lander, so the AG1
  visitor is not told the deal begins in two weeks.

Every price claim keeps the "first year" qualifier.
