Show sign-in dialog when delegating to session targets while unauthenticated

When a user tries to delegate to Copilot CLI, Cloud, or other session
targets while not signed in, trigger the sign-in/setup dialog instead of
letting the request fail with a non-actionable error.

The sign-in check is added to three entry points:
- SubmitAction.handleDelegation() for the session target picker
- CreateRemoteAgentJobAction.run() for the "Continue in..." dropdown
- CreateRemoteAgentJobFromEditorAction.run() for the editor context menu

This matches the existing Local session behavior where the setup dialog
is shown when the user's entitlement is Unknown and anonymous access is
not enabled.

Fixes #296117
