Default new stations to kiosk mode

Operator-facing stations come up in kiosk mode out of the box, with a tighter install command and a polished repo list on the New Procedure flow.

• Defaulted new station deployments to kiosk mode (full-screen operator UI on boot)
• Refactored the install command snippet so the copy-paste flow is shorter
• Polished the linked-repo list on the procedure detail page
