Request Timeout on Big File (180MB)

# Bug Report

## Problem
```
[BackgroundTask] Background Task 1 ("Called by CordovaPlugins, from -[CDVFileTransfer uploadData:command:]"), was created over 30 seconds ago. In applications running in the background, this creates a risk of termination. Remember to call UIApplication.endBackgroundTask(_:) for your task in a timely manner to avoid this.

NSURLConnection finished with error - code -1001
File Transfer Error: The request timed out.
```

### What is expected to happen?
Not timeout.

### What does actually happen?
Times out.

## Information

Using latest `master` branch code.

### Command or Code

Ensure file is large. If the timeout doesn't occur, increase file size. The current environment is in a K8's cluster, so there may be some overhead there on my end.
```
const fileURL = file:// ...
const options: FileUploadOptions = {
fileKey: 'file',
fileName: fileURL.substring(fileURL.lastIndexOf('/') + 1),
mimeType: 'text/plain',
};

// TODO Pass created uuid and version
const params: any = {};
params.value1 = 'test';
params.value2 = 'param';

options.params = params;

const ft = new FileTransferObject();
ft.upload(
fileURL,
encodeURI(`http://example.com`),
options,
);
```

### Environment, Platform, Device

K8's/Docker with iOS, iPad Pro 12.9

## Checklist

- [x] I searched for existing GitHub issues
- [x] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

Start by reproducing the 180MB upload through FileTransferObject.upload and inspect the iOS entry point named -[CDVFileTransfer uploadData:command:], focusing on the timeout and background-task messages. Compare behavior for smaller and larger files in the listed Cordova, Capacitor, and iOS environment; done means the large upload no longer fails with request timeout.
