Guide v1.0 stations to upgrade to the CLI

Stations v2.0 run on the TofuPilot CLI. The dashboard and the desktop app now point v1.0 station users to the upgrade, with step-by-step guides.

• Added a prompt on the desktop station app and the dashboard deploy page that explains the move from the v1.0 desktop station to the CLI.
• Linked the migration guide everywhere, plus a self-hosted guide for enabling realtime and deploys when the prompt detects a self-hosted instance.
• Marked the desktop station app as v1 so it is clear which stations still need to upgrade.
