No IP address in request when `directAccess: true`

Issue Description

When setting the Parse Server option directAccess: true, the request object in triggers have no IP address set.

This could be considered a characteristic of the direct access feature, but there are a few test cases that expect the IP address to be set, so it should probably be considered a bug.

https://github.com/parse-community/parse-server/blob/4b3ce20300b05b015b48efeb82d693200159911f/spec/CloudCode.spec.js#L2083-L2091

https://github.com/parse-community/parse-server/blob/4b3ce20300b05b015b48efeb82d693200159911f/spec/CloudCode.spec.js#L2468-L2483

All these tests pass, only because the test suite does not actually use the ParseServerRESTController because the test helper always sets the normal REST controller:

https://github.com/parse-community/parse-server/blob/4b3ce20300b05b015b48efeb82d693200159911f/spec/helper.js#L169

See https://github.com/parse-community/parse-server/issues/8808 for context about this override.

Steps to reproduce

1. Set Parse Server option directAccess: true.
2. Save a Parse.User.
3. The request object in Parse.Cloud.beforeSave('_User', async request => { ... }); has the property request.ip set to undefined.

Actual Outcome

request.ip set to undefined

Expected Outcome

request.ip set to localhost, e.g. 127.0.0.1 in IPv4 environments or ::1 in IPv6 environments.

Possibly just set the IP with a simple:

function getLoopbackAddress() {
  const isIPv6Supported = os.networkInterfaces().lo0?.some(iface => iface.family === 'IPv6');
  return isIPv6Supported ? '::1' : '127.0.0.1';
}

Environment

Server

• Parse Server version: 6.3.1

Start with src/ParseServerRESTController.js and the controller override in spec/helper.js, then inspect the referenced cases in spec/CloudCode.spec.js. Run the direct-access trigger tests and verify that request.ip is populated with the expected loopback address rather than undefined.
