feat: add client credentials unattended auth flow

[cristipufu]

Pull Request Overview

This PR adds a client credentials unattended authentication flow to the CLI tool.

• Introduces new CLI options (--client-id, --client-secret, --base-url) to facilitate unattended authentication.
• Implements a new authentication branch in auth() to handle client credentials and falls back to interactive mode when credentials are not provided.
• Adds a new module (src/uipath/_cli/_auth/_client_credentials.py) that encapsulates the client credentials authentication logic.

Usage Example

The external app needs the OR.Execution Orchestrator scope for package publishing.

uipath auth --client-id='12345678-c4c5-4f1f-93ff-4f5ab47d57ea' --client-secret='xxx' --base-url='https://alpha.uipath.com/account/tenant'

uipath publish --tenant

• The new client credentials authentication flow isn’t covered by existing tests. Add unit tests for authenticate() (including success, 400, 401, and network failure scenarios) to ensure reliability.

[nitpick] This inner if base_url: check is redundant because base_url was already validated above. You can remove this condition to simplify the logic.
