Fix kiosk intake routing, view names, and SignalR diagnostics

Three bugs identified:
1. Routing: /Kiosk/Intake/{token}/{action} had no matching route — 4-segment
   URL fell through the default 3-segment {controller}/{action}/{id?} route.
   Added explicit kiosk_intake route in Program.cs.

2. View names: Contact/Job/Terms/Confirmation actions returned View(model)
   which resolved to Views/Kiosk/{Action}.cshtml — those files don't exist.
   Views live in Views/Kiosk/Intake/. Fixed all six return statements.

3. Diagnostics: conn dot now starts gray ("Connecting...") and turns green
   only when SignalR actually connects. Red + message if no company ID or
   connection fails. Makes it easy to confirm the hub connection is live.
