Update a phone number business username

Requests a Business Username update for a WhatsApp business phone number. The requested username may require Meta review before it becomes active. If Meta accepts the request for review, the response status is usually pending_review; if Meta returns an error, YCloud returns the error and does not change the stored Business Username state.

The username value is a plain username without @. YCloud trims leading and trailing whitespace and normalizes the value to lowercase before validation and submission.
