Find paying clients who never made it into Drip

**Objective:** Find FreshBooks clients who signed up since `{signup-since}` (default: the last 90 days) that have no matching Drip subscriber, up to `{max-clients}` clients (default 50).

**Step 1: Read the clients from FreshBooks**

Call `freshbooks-get-client` (FreshBooks server) with `signup-date.from` set to `{signup-since}` and `max-records` set to `{max-clients}`. Keep only clients with a non-empty `email`. Note how many had no email and skip them.

**Step 2: Look each client up in Drip**

For each client email, call `drip-get-subscriber` (Drip server) with `email` set to that address, lower-cased and trimmed. Match on the email only. A person with the same name but a different email is not a match.

**Step 3: Report**

Give a table of the clients with no Drip subscriber: client id, organization, first and last name, email, signup date. Then give counts: clients checked, matched, missing, skipped for no email. List separately any Drip subscribers whose `status` is not active, with their status.

**Rules & Guidelines:**

* `freshbooks-get-client` is on the FreshBooks server; `drip-get-subscriber` is on the Drip server. Both servers must be connected.
* This prompt is read-only. Do not call `drip-add-subscriber`, `drip-update-subscriber`, `drip-add-subscriber-tag`, `freshbooks-add-client`, `freshbooks-update-client` or any other add, update or delete tool.
* Both servers take a `company` parameter; pass the company the user is authorized for on every call, and never mix companies.

**Validation:**

* If FreshBooks returns no clients, say so and stop.
* If `drip-get-subscriber` returns more than one subscriber for an email, report it as a duplicate and do not guess which is right.
* If a call fails, report which side failed and what was not checked. Do not present a partial result as complete.
