feat: implement naming convention, deployment automation, and infrastructure updates

- Add comprehensive naming convention (provider-region-resource-env-purpose)
- Implement Terraform locals for centralized naming
- Update all Terraform resources to use new naming convention
- Create deployment automation framework (18 phase scripts)
- Add Azure setup scripts (provider registration, quota checks)
- Update deployment scripts config with naming functions
- Create complete deployment documentation (guide, steps, quick reference)
- Add frontend portal implementations (public and internal)
- Add UI component library (18 components)
- Enhance Entra VerifiedID integration with file utilities
- Add API client package for all services
- Create comprehensive documentation (naming, deployment, next steps)

Infrastructure:
- Resource groups, storage accounts with new naming
- Terraform configuration updates
- Outputs with naming convention examples

Deployment:
- Automated deployment scripts for all 15 phases
- State management and logging
- Error handling and validation

Documentation:
- Naming convention guide and implementation summary
- Complete deployment guide (296 steps)
- Next steps and quick start guides
