✨ Description of new changes

📋 Overview
This PR introduces the new deploy command that integrates with the fabric-cicd library, enabling users to deploy multiple Fabric items in a single operation while addressing authentication challenges through a custom MSAL bridge implementation.

🌟 Key Features

1. Deploy Command Implementation
   New CLI Command: Added with comprehensive argument parsing
   Configuration File Support: Accepts deployment configuration files via --deploy_config_file parameter
   Target Environment: Supports environment-specific deployments with --target_env
   Parameter Override: JSON parameter support via -P flag for runtime configuration override
   Force Mode: --force flag to bypass confirmation prompts
2. CICD Library Integration
   Seamless Integration: Direct integration with fabric_cicd.deploy_with_config
   Logging Coordination: Synchronized debug logging between CLI and CICD library
   Feature Flag Management: Automatic feature flag configuration for optimal deployment behavior
   Error Handling: Comprehensive error handling with FabricCLIError wrapping
3. MSAL Bridge Authentication Solution
   Core Implementation
   MsalTokenCredential: Custom TokenCredential implementation wrapping CLI's MSAL authentication
   Scope Validation: Strict validation ensuring only SCOPE_FABRIC_DEFAULT scopes are accepted
   Multi-Auth Support: Compatible with user login, service principal, managed identity, and environment tokens
   Headless Mode: Always operates in non-interactive mode for CI/CD compatibility
   Security Features
   Scope Restriction: Security validation prevents unauthorized scope requests
   Token Reuse: Leverages existing CLI authentication without requiring re-authentication
   Automatic Refresh: MSAL silent acquisition handles token refresh automatically

Deployment Workflow & Integration:

• Introduce a deploy command delegate directly to the fabric-cicd library via the updated deploy_with_config_file function in fab_fs_deploy_config_file.py, including feature flag setup, debug logging, and improved error handling with custom exceptions.

Dependency Updates:

• Added azure-core and fabric-cicd as dependencies in pyproject.toml and requirements-dev.txt to support new deployment features and Azure authentication integration.

Authentication & Token Handling:

• Introducing MSAL token bridge to handle the authenticating in fabric-cicd

Testing Improvements:

• Updated test configuration to enable live recording mode for pytest, and improved test request patching to support JSON string parameters for compatibility with fabric_cicd. [1] [2]

Error Handling:

• Added a new error constant ERROR_IN_DEPLOYMENT to fab_constant.py for clearer error reporting during deployment failures.
