ForgeChat Desktop v3.8.4 — Full audit fixes (webhooks, calls, speaking indicator)
Resync of the desktop app with today's full-codebase audit fixes (server 3.180.0 / client 3.528.0):
- Webhook and GitHub-integration messages no longer show the real account/owner username after a reload, search, pin, or forward -- they keep their proper webhook/GitHub name.
- DM voice/video calls now tolerate a brief network blip instead of hanging up instantly (same 4s grace + ICE restart already used by server voice channels).
- The remote participant "speaking" indicator (green ring, Focus-mode auto-follow) now actually reacts to real audio instead of being hardcoded to local-user-only.
- Minor cleanup-map and dead-code fixes in the voice call store.
