Edit an intake

Edit project name, due date, chase cadence, and the client's name/phone/language/timezone on an existing intake — the alternative used to be deleting it and creating a new one, which re-sends the invitation. client.email cannot be changed here: the portal link and magic token are bound to it, so add, remove, or reinstate addresses through the recipients endpoints instead. Every field is optional but at least one is required (400 otherwise); null clears owner_note, client_brief, due_date and chase_at_time, omitting a field always leaves it untouched. On a sent, in_progress or stalled intake, changing any cadence-related field (chase_schedule, chase_interval, chase_interval_unit, chase_at_time, max_reminders, respect_quiet_hours, client.timezone, due_date) cancels every still-scheduled reminder and re-plans under the new settings; attempt numbering is unaffected. Raising max_reminders (or setting it to "unlimited") past the number of reminders already sent un-stalls a stalled intake and resumes automatic chasing. Refused with 409 conflict on an archived intake.
