Unauthorized route migration for routes owned by stack-monitoring (#1…

…98372)

### Authz API migration for unauthorized routes

This PR migrates unauthorized routes owned by your team to a new
security configuration.
Please refer to the documentation for more information: [Authorization
API](https://docs.elastic.dev/kibana-dev-docs/key-concepts/security-api-authorization)

### **Before migration:**
```ts
router.get({
  path: '/api/path',
  ...
}, handler);
```

### **After migration:**
```ts
router.get({
  path: '/api/path',
  security: {
    authz: {
      enabled: false,
      reason: 'This route is opted out from authorization because ...',
    },
  },
  ...
}, handler);
```

### What to do next?
1. Review the changes in this PR.
2. Elaborate on the reasoning to opt-out of authorization.
3. Routes without a compelling reason to opt-out of authorization should
plan to introduce them as soon as possible.
2. You might need to update your tests to reflect the new security
configuration:
  - If you have snapshot tests that include the route definition.

## Any questions?
If you have any questions or need help with API authorization, please
reach out to the `@elastic/kibana-security` team.
