docs(platform): socket sessions move to /api/v1 and take a personal access token

[ozsay]

Summary

The Platform SDK README described the white-label socket-session API at its old path and as workspace-key only. base44-dev/apper#31673 moves it and adds personal access tokens:

• POST /api/service/socket-sessions → POST /api/v1/socket-sessions
• PUT/DELETE …/{session_id}/rooms/{app_id} → …/{session_id}/apps/{app_id}
• Your backend can authenticate with a personal access token (the apps its owner can edit) or a workspace API key with apps:watch, both as Authorization: Bearer. The workspace needs the Builder plan or higher.

No code change: the client only reads the session body (session_token, socket_url, socket_path), which is unchanged. asyncapi.json picks up the new wording through the hourly sync.

Merge order

Merge after base44-dev/apper#31673 is deployed, since until then the new path doesn't exist.
