Implement Token Based Auth Controller for API token authentication

[Copilot]

• Create AbstractTokenController extending AbstractBasicController
• Implement token-based authentication without authenticate/logout flow
• Configure Bearer header by default
• Create TokenAuthController concrete class
• Add test file for AbstractTokenController
• Run tests to verify implementation
• Add usage documentation to AbstractTokenController
• Remove unused imports
• Support both 'token' and 'api_token' credential properties for backward compatibility

<issue_title>Implement a Token Based Auth Controller</issue_title>
<issue_description>Many APIs that work for server to server integration simply provide an API Token that is configured in the environment and passed along via standard Bearer Authorization header like an Oauth Token, without the Login/Logout flow. We need an AuthController for Token Based authentication added for this common scenario.</issue_description>

@copilot need to allow setting of token via multiple properties for backward compatibility with previous implementations of this repo that built it out already.

Implemented support for both 'token' and 'api_token' properties in setCredentials() method. Added comprehensive tests including precedence behavior when both properties are provided.
