Revised the main README to clarify the mobile app structure and added a detailed README for the mobile apps. Introduced a new 'gen:all' script in Melos to run both localization and build_runner generation, and updated the info script to reflect this addition.
Updated Makefile, mobile.mk, and melos.yaml to centralize mobile app build, start, and code generation commands using Melos scripts. Added info and install-melos commands for easier onboarding and workspace setup. Documentation updated to reflect staff app naming and new command structure.
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.
