Add multiple-session support: run several independent encrypted chats at once

Each conversation now runs its own WebRTC session with separate keys and SAS verification, so chats never mix. Adds a side panel to switch between open chats with unread badges, a New chat action that leaves existing chats connected, per-chat local labels stored only on this device, and an availability status (Available, Away, Busy, Invisible) shared end-to-end with connected peers. Also includes vendored Prism syntax highlighting, more reliable PWA update handling, and offline send queueing fixes. Version 4.10.0.

+**Multiple conversations**
+- Run several independent chats at the same time. Every conversation gets its own encrypted session, keys and verification, so two chats can never mix.
+- A side panel lists your open chats with unread badges. Switching is instant, and starting a new chat leaves the others connected.
+- Set your availability (Available, Away, Busy or Invisible) and connected peers can see it. You can also give each chat a private label that is stored only on your device and is never sent to the other side.

 ** File transfer**
 - Consent-gated, end-to-end encrypted transfers with resumable, per-chunk progress.
 - Strict file-type allowlist; executable and scriptable formats are rejected.
