feat(waiter): native app runs each venue's own UI bundle (self-hosted updater)

@capgo/capacitor-updater (MPL-2.0) in manual mode: autoUpdate off,
stats/update/channel URLs empty (nothing contacts Capgo), appReadyTimeout
15s (auto rollback), resetWhenUpdate (APK update → built-in bundle, venue
bundle re-fetched), autoDeletePrevious off (we keep one per venue).

src/native/bundles.js syncVenueBundle():
- manifest fetched over the pinned TLS link; zip downloaded natively over
  the LAN HTTP port with the MANDATORY sha256 check - a tampered zip never runs
- applied at once only when nobody is mid-service (after pairing / venue
  switch, or no one logged in); otherwise staged with next() → applied at the
  next background/restart; never a mid-service reload
- APK too old for the bundle (min_shell_build) → skipped + update banner
  linking to the venue's /downloads/xenia-waiter.apk
- a rolled-back version is blocklisted (attempt tracking + grace window) -
  without it the app re-applied the still-advertised broken bundle in a loop
- server without bundles (404) → built-in UI; bundles no venue needs deleted
BundleSync: notifyAppReady on start; sync at start, on resume, every 30 min.
saveVenue merges fields (bundleVersion); switchVenue flags immediate apply.

E2E (emulator vs two isolated venue stacks): fresh pairing applies the venue
bundle and it stays healthy; logged-in update staged, applied after
background, session kept; tampered zip refused; shell-too-old banner;
broken bundle rolled back automatically and not retried (80s + resume);
two venues each run their own bundle, round trips served from cache with 0
downloads, stale bundles cleaned; no *.capgo.app traffic. Step 5/7-era
rediscovery + cold-start suites and web modes still pass.
