feat(verification): add user identity verification system

Add comprehensive user verification feature including:
- VerificationGuideScreen: Guide screen explaining the verification process
- VerificationFormScreen: Form for submitting verification applications
- VerificationSettingsScreen: Settings page to view verification status
- verificationService: API service for verification operations
- verificationStore: State management for verification state
- DTOs: Types for verification records, status, and admin operations

The system supports multiple identity types (student, teacher, staff, alumni, external)
and includes both user-facing and admin-facing functionality.
