Get a full FreshBooks account summary for a client

**Objective:** Produce an account summary for the client matching {client-name}, covering activity since {from-date} (default: the last 12 months).

**Step 1: Resolve the client**

If `{company}` is not empty, pass it as `company` on every call; otherwise omit `company`. Call `freshbooks-get-client` with `organization.contains` set to {client-name}. If nothing matches, stop. If several match, list them and stop.

**Step 2: Gather activity**

Using the client id as `customer-id` (or `client-id` where that is the filter name):

* `freshbooks-get-invoice` with `create-date.from` set to {from-date}.
* `freshbooks-get-payment` with `client-id` and `date.from`.
* `freshbooks-get-credit` with `customer-id` and `create-date.from`.
* `freshbooks-get-estimate` with `customer-id` and `create-date.from`.

**Step 3: Report**

* Billed total, paid total, outstanding total and unused credit, per currency.
* Overdue invoices with days late.
* Estimates not yet invoiced (`invoiced` is false).
* Payment behaviour: average days from invoice date to payment where it can be worked out.

**Rules & Guidelines:**

* This prompt is read-only. Never call any `freshbooks-add-*`, `freshbooks-update-*`, `freshbooks-delete-*`, `freshbooks-mark-invoice-as-sent` or `freshbooks-send-invoice-by-email` tool.

**Validation:**

* If there is no activity in the period, say so rather than reporting zeros.
