Explain credential options to invited members
New workspace members now see whether runs use a shared credential or Sinatra's key, with a path to connect their own subscription.
Joined workspaces stay immediately accessible. The new overview message appears once per workspace, can be dismissed, and explains the credential setup before a member starts work.
It does not change which credential runs use; it makes the workspace's current setup visible and keeps the optional subscription flow in context.
