Subject: [PATCH] feat: improve webtorrent fallback reliability

- Increased `PROBE_TIMEOUT_MS` in `js/gridHealth.js` to 20s to reduce false negatives in peer detection.
- Relaxed the peer check in `js/app.js` to allow forcing a switch to WebTorrent even if the liveliness checker reports 0 peers (showing a warning instead of an error).
- Added `tests/verify_app_switch.mjs` to validate the UI logic change.
