feat: implement template cloning and extended item data retrieval

Browse source 
- Extend Template and ZabbixItem types in GraphQL schema to support full item hierarchy and cloning.

- Update ZabbixQueryTemplatesRequest in src/datasources/zabbix-templates.ts to fetch comprehensive item configurations (type, status, history, delay, units, preprocessing, tags).

- Implement raw value resolvers for ZabbixItem.type_int and ZabbixItem.status_int in src/api/resolvers.ts.

- Add new MCP operations: mcp/operations/getTemplates.graphql and mcp/operations/importTemplates.graphql for template management via AI agents.

- Add 'Cloning a Template with Items' recipe to docs/howtos/cookbook.md.

- Update src/test/template_query.test.ts to ensure compatibility with extended datasource output.

## 🍳 Recipe: Cloning a Template with Items
This recipe guides you through cloning an existing Zabbix template, including all its items and their configurations, into a new template using the GraphQL API and MCP.
### 📋 Prerequisites
- Zabbix GraphQL API is running.
- You have the technical name of the source template.
### 🛠️ Step 1: Query the Source Template
Retrieve the source template's details and all its items.
**GraphQL Query**:
```graphql
query GetSourceTemplate($name: String!) {
templates(name_pattern: $name) {
host
name
items {
itemid
name
key_
type_int
value_type
status_int
history
delay
units
description
preprocessing
tags
master_itemid
}
}
}
```
### ⚙️ Step 2: Prepare the Clone Configuration
1. **Technical Names**: Choose a new technical name (`host`) and visible name (`name`) for the clone.
2. **Item Mapping**: Map the source items to the `items` array in the `importTemplates` mutation.
3. **Resolve Master Items**: For dependent items (where `master_itemid` > 0), find the source item with the matching `itemid` and use its `key_` as the `master_item.key` in the new item definition.
### 🚀 Step 3: Execute `importTemplates` Mutation
Execute the mutation to create the clone.
```graphql
mutation CloneTemplate($templates: [CreateTemplate!]!) {
importTemplates(templates: $templates) {
host
templateid
message
}
}
```
### ✅ Step 4: Verification
Verify that the cloned template exists and has the expected items.
```graphql
query VerifyClone($host: String!) {
templates(name_pattern: $host) {
templateid
host
items {
name
key_
}
}
}
```
### 🤖 AI/MCP
AI agents can use the following MCP tools to automate this:
- **GetTemplates**: To fetch the source template and its hierarchical item structure.
- **ImportTemplates**: To provision the new cloned template.

## 🍳 Recipe: Setting up GraphQL MCP for AI Agents
This recipe guides you through setting up the Model Context Protocol (MCP) server to enable AI agents like **Junie** or **Claude** to interact with your Zabbix data through the GraphQL API.
