This commit addresses several critical issues across the mobile monorepo:
1. Centralized Error Handling: Integrated DataErrorHandler mixin into all repository implementations, ensuring consistent mapping of Data Connect exceptions to domain AppExceptions.
2. Build Stabilization: Fixed numerous type mismatches, parameter signature errors in widgets (e.g., google_places_flutter itemBuilder), and naming conflicts (StaffSession, FirebaseAuth).
3. Code Quality: Applied 'dart fix' across all modified packages and manually cleared debug print statements and UI clutter.
4. Mono-repo alignment: Standardized Data Connect usage and aliasing ('dc.') for better maintainability.

Reorganized and clarified dependency sections in multiple pubspec.yaml files, grouping architecture and feature packages. Updated import statements in AuthRepositoryImpl for direct usage of types. Added missing dependencies to client authentication. Removed obsolete documentation and summary files from design_system and client home packages.
Relocated all app directories (client, design_system_viewer, staff) and their contents under the new 'apps/mobile' path. This change improves project organization and prepares for future platform-specific structuring.
