[UX] Permission Onboarding Flow

[sunpl13]

Overview

Implement the Onboarding flow to request necessary permissions, specifically "Always Allow" for location.

Requirements

• Explain why background location is needed (Geofencing).
• Request Flow:
  1. Foreground Location (When in use).
  2. Background Location (Always allow) promotion.
  3. Notification Permission.
• Handle "Denied" states gracefully.
