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.

Sanitize message text at the debounce enqueue boundary and add an
independent guard in combineDebounceEntries(). Prevents TypeError when
a queued entry has null text that reaches .trim() during flush.
Add regression test: enqueue null-text entry alongside valid message,
verify flush completes without error and valid message is delivered.
Fixes#35777
* fix(extensions): route fetch calls through fetchWithSsrFGuard
Replace raw fetch() with fetchWithSsrFGuard in BlueBubbles, Mattermost,
Nextcloud Talk, and Thread Ownership extensions so outbound requests go
through the shared DNS-pinning and network-policy layer.
BlueBubbles: thread allowPrivateNetwork from account config through all
fetch call sites (send, chat, reactions, history, probe, attachments,
multipart). Add _setFetchGuardForTesting hook for test overrides.
Mattermost: add guardedFetchImpl wrapper in createMattermostClient that
buffers the response body before releasing the dispatcher. Handle
null-body status codes (204/304).
Nextcloud Talk: wrap both sendMessage and sendReaction with
fetchWithSsrFGuard and try/finally release.
Thread Ownership: add fetchWithSsrFGuard and ssrfPolicyFromAllowPrivateNetwork
to the plugin SDK surface; use allowPrivateNetwork:true for the
Docker-internal forwarder.

* fix(extensions): improve null-body handling and test harness cleanup

* fix(bluebubbles): default to strict SSRF policy when allowPrivateNetwork is unset
Callers that omit allowPrivateNetwork previously got undefined policy,
which caused blueBubblesFetchWithTimeout to fall through to raw fetch
and bypass the SSRF guard entirely.
