fix: (MMS-1789) bridge api called when external services disabled

[ghgoodreau]

Description

Bridge API gets called even when all privacy toggles are disabled:

https://bridge.api.cx.metamask.io/getAllFeatureFlags

Related issues

Fixes: checks if external services are enabled (Basic Functionality toggle) before calling this API in the useBridging hook.

Manual testing steps

1. Start onboarding through the MetaMask wallet.
2. During onboarding, toggle the security feature 'Basic Functionality' OFF.
3. Observe network calls to ensure this endpoint is not hit.
