Webhook channels (LINE, Zalo, Nextcloud Talk, BlueBubbles) are
incorrectly flagged as stale-socket during quiet periods because
snapshot.mode is always undefined, making the mode !== "webhook"
guard in evaluateChannelHealth dead code.
Add mode: "webhook" to each webhook plugin's describeAccount and
propagate described.mode in getRuntimeSnapshot.

* fix(gateway): isolate channel startup failures to prevent cascade
When one channel (e.g., WhatsApp) fails to start due to missing runtime
modules, it should not block other channels (e.g., Discord) from starting.
Changes:
- Use Promise.allSettled to start channels concurrently
- Catch individual channel startup errors without affecting others
- Add startup summary logging for observability
Before: Sequential await startChannel() - if one throws, subsequent
channels never start.
After: Concurrent startup with per-channel error handling - all channels
attempt to start, failures are logged but don't cascade.
Fixes: P0 - WhatsApp runtime exception no longer blocks Discord startup
* fix(gateway): keep channel startup isolation sequential
* fix: isolate channel startup failures (#54215) (thanks @JonathanJing)
