Adjust File Headers to Use Proper Container-Compose License

[Copilot]

• Update license headers in all Swift files in /Sources directory
  • Replace incorrect "Apple Inc. and the container project authors" with "Morris Richman and the Container-Compose project authors"
  • Add proper Apache 2.0 license header to Application.swift which previously lacked it
  • Remove old file comment header from Application.swift per feedback
  • Keep existing file-specific comment headers (Created by, etc.) in other files
• Verify all 26 Swift files have been updated correctly
• Complete license header updates for the Container-Compose project

Fixes #16

<issue_title>Adjust File Headers to be Proper Licenses</issue_title>
<issue_description>The File headers in /Sources currently are a left over artifact from when this project was a Pull Request directly for Apple container. This is no longer the case and was never licensed to be Apple's code. Therefore the headers must be changed to this:

//===----------------------------------------------------------------------===//
// Copyright © 2025 Morris Richmna and the Container-Compose project authors. All rights reserved.
//
// Licensed under the Apache License, Version 2.0 (the "License");

It is a fairly simple change, just a matter of doing it.</issue_description>

@copilot There was a typo originally. It is Morris Richman not Morris Richmna.
