feat(gateway-auth): enhance authentication configuration and credential retrieval (#292)

- Added support for specifying authentication mode ('token' or 'password') in the gateway configuration.
- Updated `getDetectedGatewayToken` function to return the appropriate credential based on the selected mode.
- Improved security scan checks for gateway authentication, ensuring both token and password modes are validated correctly.
