feat: add interactive OAuth authentication to dev server

Implements PKCE-based OAuth flow matching the Python SDK's `uipath auth` CLI command. A temporary callback server receives the token from the browser, resolves tenants, and writes credentials to .env and os.environ. Includes session persistence across restarts, automatic token expiry detection with re-auth support, and a configurable flag to disable auth in deployments.
