Handoff's booking screen has no free-text input for the person doing the booking. An SDR who knows something the AE needs before the call, context from the conversation, a warning, a specific ask, has nowhere to put it during scheduling, so they book the meeting and then go add the note somewhere else: the calendar event by hand, a Slack message, or a CRM field.

Requested behavior: a free-text notes input on the Handoff booking flow, with the entered text written to the meeting invite description and, separately, to a mappable field on the Salesforce Event.
