Problem:
After accepting the T&C modal during Spider registration, the modal closes and the UI gives no feedback while the backend process runs (30+ seconds), making it appear broken.
Desired outcome:
Users see clear visual feedback that registration is in progress and, ideally, which step is currently executing.
Proposed change:
Display a progress indicator after T&C acceptance — at minimum a spinner, ideally stepped status messages (e.g. "Activating Plan", "Setting up satellite connection", "Setting up cellular connection").
