feat: Messenger + Inbox on the AppShell data door + live IIOS socket

New "Communication" area in the dashboard, built on the existing appshell-sdk wiring
(useQuery/sdk.command) like Team, with the IIOS MessageSocket for live streaming.

- messenger-api.ts / inbox-api.ts: mock (demo) + live (crm.messenger.* / crm.inbox.*)
  behind one interface, switched by isShellConfigured().
- messenger-socket.tsx: MessengerSocketProvider — one IIOS MessageSocket per panel
  (openThread history + live on("message") + send). REST 4s poll is the automatic
  fallback when the socket isn't connected.
- messenger.tsx: conversation list ⇄ thread + composer + new-chat people picker
  (DM 1 person / group 2+); inbox.tsx: filterable feed with Done/Snooze/Archive.
- sidebar: Communication group (Messenger + Inbox, always-visible); dashboard: panel switch.
- .npmrc: add the @insignia Gitea registry for @insignia/iios-kernel-client.

Works on mock immediately; goes live once NEXT_PUBLIC_SUPABASE_URL + the BFF + be-crm are set.
tsc clean; next build passes.

+// the be-crm data door (crm.messenger.*). Conversation list ⇄
+// thread view + composer, with a "new chat" people picker that
+// creates a DM (1 person) or group (2+). DM-vs-group and who-can-
+// chat are enforced server-side by IIOS/OPA; this is just UI.
+// Data comes from useMessengerData()/useThread(): local mock when
+// the Shell isn't configured, live be-crm when it is.
