Remove Start Inspection button from Attik mobile app (Spectora not supported)

Objective

• Remove the Start Inspection button from the inspection detail screen in the Attik mobile app so inspectors are not shown a non-functional control.
• Preserve the View in Attik action and footer layout; inspectors continue to start reports manually in the Spectora app.

Background

• The inspection detail screen in the Attik mobile app shows a Start Inspection button that was intended to open Spectora. Spectora does not support being opened from the app in this way, so the button currently does nothing (the handler is a no-op with a TODO).
• Product feedback: remove the button and rely on inspectors starting the report manually in the Spectora app to avoid confusion and support requests.

Scope

Mobile (Attik mobile app)

• The Start Inspection button and its handler live on the inspection detail screen in app/(app)/inspection/[id].tsx.
• Remove the Start Inspection TouchableOpacity (and its icon/label) and the handleOpenSpectora handler.
• Keep the View in Attik button and the footer BlurView / footerRow; adjust layout or styles as needed so the single remaining button looks correct.
• No backend or frontend (web) changes are in scope.
