fix(call): ignore stale roomJoined events that fire before joinRoomndCall

[tareko]

When the app launches and immediately joins an existing call, the WebSocket may already be connected from a previous session. The server sends a stale roomJoined event before joinRoomAndCall() is called, causing performCall() to fire prematurely. Later when joinRoomAndCall runs, the WebSocket does a local join and the server never re-sends the participant list. The call stays stuck in JOINED and never transitions to IN_CONVERSATION.

Add joinRoomInitiated flag to guard the roomJoined handler against stale events. Only process roomJoined after joinRoomAndCall has been called.

This fixes Issue #6044 . I used OpenCode and GLM-5.1 to debug and fix this bug.
