Clarify procedure and station setup tabs
The Get Started tabs on procedure and station pages now say what each integration path actually does, so new users can pick between the CLI and the SDKs at a glance.
- Renamed the setup tabs to "TofuPilot runs your tests" and "Your code sends results" on both pages, with icons matching each path
- Improved the station setup descriptions: supported frameworks and SDK languages are now listed inline in a single readable sentence
- Updated the API key empty state to a shorter, clearer call to action
