feat(supply-depot): show installed version on cards + make Update pill stand out

Two card tweaks for the update workflow:

- Show the installed image tag next to the powered-by name (e.g. "Kiwix ·
  3.7.0"), so the running version is visible at a glance. Only rendered for
  installed apps; falls back to just the version when powered_by is unset.
- Change the "Update available" pill from a muted light-green tint to a solid
  desert-orange fill with white text, so an available update actually draws
  the eye instead of blending into the card.
