Andreas Hilbig a01bfabfba docs: refactor documentation and upgrade to Node.js 24

This commit upgrades the project to Node.js 24 (LTS) and performs a major refactoring of the documentation to support both advanced users and AI-based automation (MCP).

Changes:
- Environment & CI/CD:
  - Set Node.js version to >=24 in package.json and .nvmrc.
  - Updated Dockerfile to use Node 24 base image.
  - Updated @types/node to ^24.10.9.
- Documentation:
  - Refactored README.md with comprehensive technical reference, configuration details, and Zabbix-to-GraphQL mapping.
  - Created docs/howtos/cookbook.md with practical recipes for common tasks and AI test generation.
  - Updated docs/howtos/mcp.md to emphasize GraphQL's advantages for AI agents and Model Context Protocol.
  - Added readme.improvement.plan.md to track documentation evolution.
  - Enhanced all how-to guides with improved cross-references and up-to-date information.
- Guidelines:
  - Updated .junie/guidelines.md with Node 24 requirements and enhanced commit message standards (Conventional Commits 1.0.0).
- Infrastructure & Code:
  - Updated docker-compose.yml with Apollo MCP server integration.

🔐 Roles and Permissions Extension

The API implements a permission system using Zabbix template groups:

Permission Template Groups

Template groups with prefix Permissions/ (configurable via ZABBIX_PERMISSION_TEMPLATE_GROUP_NAME_PREFIX) are used for permissions
Users gain permissions by being assigned to user groups that have access to these permission template groups

Available Permissions

The system supports three permission levels defined in ../../schema/api_commons.graphql:

DENY: Explicitly denies access (supersedes other permissions)
READ: Allows viewing/reading access
READ_WRITE: Allows both reading and writing (implies READ permission)

Permission Object Names

Permission object names map to Zabbix template group paths: Permissions/{objectName}

GraphQL Permission Queries

# Check if current user has specific permissions
query HasPermissions {
  hasPermissions(permissions: [
    { objectName: "hosts", permission: READ },
    { objectName: "templates", permission: READ_WRITE }
  ])
}

# Get all user permissions
query GetUserPermissions {
  userPermissions(objectNames: ["hosts", "templates"])
}

Setting Up Permissions

Create template groups with the prefix Permissions/ (e.g. Permissions/hosts, Permissions/templates)
Assign these template groups to user groups in Zabbix with appropriate permission levels
Users in those user groups will inherit the permissions

Detailed Permission Usage Examples

For comprehensive examples of permission usage patterns, see ../../schema/api_commons.graphql which contains detailed documentation in the PermissionRequest input type comments, including real-world examples of how to model permissions for buttons, status controls, and application features.

See also ../queries/sample_import_permissions_template_groups_mutation.graphql for examples of importing permission template groups.
