Value-grid reorder + testimonial timeframe + sideload back to GH releases

- Value-grid: top row now starts with the key-ownership pitch
  (signing key → offline verification → sell however you want).
  Renamed and rewrote the prior "Bitcoin payments, your store" box
  to "Payment channels you control" and moved it to the bottom-left.
- SeasonsOfLearning testimonial: tightened the timeframe from
  "October → January" to "over a weekend → two weeks later" so the
  speed-to-launch story lands harder.
- Sideload link points at github.com/keysat-xyz/keysat/releases/latest
  now that the repo is public. files.keysat.xyz stays as the
  canonical s9pk host for the StartOS registry's package-add URL.
