Add MongoDB Atlas Alerts List Tool

This PR adds a new tool to list alerts from MongoDB Atlas projects. The tool provides a tabular view of alerts with their status, creation time, and other relevant details.

Changes

• Added ListAlertsTool class to handle listing alerts from Atlas projects
• Added listAlerts method to the Atlas API client
• Added OpenAPI type definitions for the alerts endpoint
• Added integration tests for the new tool
• Added the tool to the list of available Atlas tools

Testing

The changes include integration tests that verify:

• Tool metadata and schema validation
• Table formatting of alert results
• Proper error handling for projects with no alerts

Example Usage

// List alerts for a project
await mcpClient.callTool({
    name: "atlas-list-alerts",
    arguments: { projectId: "your-project-id" }
});

The tool returns alerts in a table format with the following columns:

• Alert ID
• Status (OPEN/CLOSED/CANCELLED)
• Created (timestamp)
• Updated (timestamp)
• Type (event type name)
• Summary

API Reference
