Add Deploy mcp sub commands

[mengyimicro]

Add Deploy MCP subcommands and refactor deployment architecture

This commit introduces a modular deployment system for the Agent365 DevTools CLI
with separate subcommands for application and MCP tool permission deployment.

Key Features Added:

New Subcommands:

• a365 deploy app - Deploy only application binaries to Azure App Service
• a365 deploy mcp - Deploy/update only MCP server scopes and permissions
• Enhanced main a365 deploy command now performs both operations sequentially

Architecture Improvements:

• Refactored duplicate code into reusable helper methods:
  • ValidateDeploymentPrerequisitesAsync() - Common config/Azure validation
  • DeployApplicationAsync() - Application deployment logic
  • DeployMcpToolPermissionsAsync() - MCP permissions management
  • HandleDeploymentException() - Standardized error handling

MCP Integration:

• Added OAuth2 permission grants management
• Implemented inheritable permissions configuration
• Added admin consent automation for agent identities
• Integrated with toolingManifest.json for scope requirements

Enhanced User Experience:

• Improved dry-run output with step-by-step preview
• Better error messages and user guidance
• Consistent logging and progress reporting across all deployment modes
• Maintained backward compatibility with existing deployment workflows

Code Quality:

• Eliminated ~60 lines of duplicated code
• Improved maintainability and testability
• Applied DRY principle throughout deployment logic
• Enhanced error handling consistency

Pull Request Overview

This PR introduces a modular deployment system for the Agent365 DevTools CLI with separate subcommands for application and MCP tool permission deployment. The changes add a365 deploy app and a365 deploy mcp subcommands while maintaining backward compatibility with the main a365 deploy command that runs both operations sequentially.

Key Changes:

• Added new GraphDeleteAsync and ReplaceOauth2PermissionGrantAsync methods to GraphApiService for OAuth2 permission management
• Refactored DeployCommand to extract reusable helper methods (ValidateDeploymentPrerequisitesAsync, DeployApplicationAsync, DeployMcpToolPermissionsAsync)
• Standardized logging bullet points from • to - across multiple files for consistency
