Make booking source immediately visible at the top of inquiries in Inbox

Problem Statement: Currently, the platform source (e.g., Booking.com) is not prominently displayed on the messaging page for inquiries. Users must rely on small badges or indirect notices to identify the source.

Impact: This lack of visibility can lead to confusion and security concerns; for example, a user may mistake a platform inquiry for a direct anonymous booking, which can appear suspicious or untrustworthy.

Proposed Solution: Add a clear, prominent label (e.g., 'Platform: Booking.com') appearing right at the top of the messaging page and details panel for inquiries.

Unlock: This will allow hosts to immediately identify the origin of an inquiry before it is confirmed, reducing suspicion and improving operational efficiency.
