See one client's FreshBooks balance and Mailchimp status together

**Objective:** Build one profile of the FreshBooks client with email `{client-email}`: what they owe and have paid, and how they stand in Mailchimp. Use company `{company}` in FreshBooks if given.

**Step 1: Find the client in FreshBooks**

Call `freshbooks-get-client` (freshbooks server) with `email` set to `{client-email}` (and `company` if given). If it returns more than one client, list them and stop. If none, say the client is not in FreshBooks and stop.

**Step 2: Get their billing position (freshbooks server)**

Take `id` from the client and call `freshbooks-get-invoice` with it as `customer-id`, then `freshbooks-get-payment` with it as `client-id`. Total the invoiced amount, the outstanding amount and the payments received, and note the latest payment date.

**Step 3: Find them in Mailchimp**

Call `mailchimp-get-list-member` (mailchimp server) with `email` set to the client's `email`. If nothing comes back, report the client as present in FreshBooks and absent from Mailchimp, then skip to Step 5. For each list returned, note `list-name`, `status`, `tags` and `rating`.

**Step 4: Recent engagement (mailchimp server)**

Call `mailchimp-get-campaign-email-activity` with `email-address` set to the same email, `max-records` 50. Summarise the opens, clicks and bounces and the most recent activity date.

**Step 5: Report**

One block: client name and organization, total invoiced, outstanding, total paid, each Mailchimp list with its status, recent engagement, and a one-line note if the picture is unusual (for example a large outstanding balance on a client who is unsubscribed).

**Rules & Guidelines:**

* `freshbooks-get-client`, `freshbooks-get-invoice` and `freshbooks-get-payment` are on the freshbooks server. `mailchimp-get-list-member` and `mailchimp-get-campaign-email-activity` are on the mailchimp server.
* Match on email only, case-insensitive. Do not match on name.
* This is read-only. Do not call any add, update or delete tool on either server.

**Validation:**

* If the client has no email in FreshBooks, say so and stop.
* If the two systems hold different spellings of the name for the same email, report both.
