* 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.

Nextcloud Talk's ChecksumVerificationService verifies HMAC against the
extracted message/reaction text, not the full JSON body. This fixes 401
authentication errors when sending messages via the bot API.
- sendMessageNextcloudTalk: sign 'message' text only
- sendReactionNextcloudTalk: sign 'reaction' string only
