"""CRM API client for the intake bot's write-back leg.

The bot authenticates as a dedicated service user (Bearer JWT via /api/auth/login — the CRM
has no service-key path) and reuses the CRM's OWN canonical write endpoint
(/api/fundraising/log-communication) for both new-investor and existing-note cases, rather
than mutating the grid itself. That endpoint creates the grid row (create_investor_if_missing),
upserts the contact, logs the communication, appends a visible note, and re-syncs the
relational tables + audit — exactly as a UI grid edit would. We only tag provenance
(source="matrix_intake"). The payload builder is a pure function so it's unit-tested offline.
