Implement settings server with monitoring functionality for Web GUI Tools

[Copilot]

This PR implements a new settings service focused on monitoring functionality to support Web GUI Tool backend requirements as requested in the issue.

Overview

The implementation adds a complete settingsserver module to the PULLPIRI project that provides REST APIs for managing monitoring configurations. The service runs on port 47007 and offers full CRUD operations for monitoring settings along with system status endpoints.

Key Features

REST API Endpoints

• Monitoring Settings Management: Complete CRUD operations
  • GET /api/monitoring/settings - List all settings
  • GET /api/monitoring/settings/{id} - Get specific settings
  • POST /api/monitoring/settings - Create new settings
  • PUT /api/monitoring/settings/{id} - Update settings
  • DELETE /api/monitoring/settings/{id} - Delete settings
• System Status: GET /api/monitoring/status - Real-time monitoring status

Configuration Structure

The service manages monitoring settings with the following structure:

{
  "id": "string",
  "monitoring_interval": 30,
  "container_monitoring_enabled": true,
  "resource_alert_threshold": 80,
  "data_retention_days": 30,
  "detailed_logging": false
}

Technical Implementation

• Thread-safe storage with in-memory HashMap (production-ready for etcd integration)
• Input validation for all configuration parameters
• CORS support for web application integration
• JSON-based APIs compatible with modern web frameworks
• Proper error handling with appropriate HTTP status codes
• Default settings automatically initialized on startup

Integration

• Follows existing PULLPIRI architecture patterns (similar to apiserver)
• Uses common configuration system and error handling
• Integrates seamlessly with the workspace build system
• Added to server workspace in src/server/settingsserver/

Testing & Documentation

• 21 comprehensive unit tests covering all functionality
• Manual API testing verified with curl commands
• Complete documentation with usage examples
• Architecture overview and integration guide

The service is immediately usable by Web GUI Tools for configuring monitoring settings in PULLPIRI deployments.

Fixes #169.

@copilot HLD 요구사항을 충족할 수 있도록 만들어줘. settingsservice.md
리뷰해보니까 REST API 구현된 내용과 요구사항이 달라. 다시 한번 확인해보고 수정해.

I cannot access the settingsservice.md document due to network restrictions. Could you please specify which parts of the REST API implementation don't match the HLD requirements? This will help me make the necessary corrections to align with the specifications.
