refactor(scripts/games): array + loop, flathub remote check, failure summary

Three things were wrong with the old script:

- One line had a duplicate `flathub` argument (`flatpak install ...
  flathub flathub org.gnome.Crosswords`). Flatpak tolerated it; still
  a typo.
- Nothing added the flathub remote, so a fresh machine without it would
  fail on every line.
- 24 nearly identical `flatpak install` lines with no central handling
  if one app failed.

I moved the app IDs into a single `APPS=()` array (sorted) and looped.
The script now runs `flatpak remote-add --if-not-exists --user flathub
https://flathub.org/repo/flathub.flatpakrepo` up front, collects any
failed apps into a `failed` array, and prints a summary plus a non-zero
exit at the end if anything didn't install. I used `set -uo pipefail`
rather than `-euo` on purpose so a single failed install doesn't abort
the rest of the run.
