Catch FreshBooks bills already paid in Ramp

**Objective:** List FreshBooks bills with an outstanding balance of at least `{min-outstanding}` (default 0.01), due on or before `{due-by}` (default today), and check each one's state in Ramp.

**Step 1: Read open bills (FreshBooks server)**

Call `freshbooks-get-bill` with `outstanding.min` set to `{min-outstanding}` and `due-date.to` set to `{due-by}`. Set `max-records` to 100. If `{company}` is given, pass it as `company` on every FreshBooks call; otherwise omit it. Keep bill number, vendor ID, total, outstanding and due date. Call `freshbooks-get-vendor` with each distinct `vendor-id` as `id` to get the vendor name.

**Step 2: Look each bill up in Ramp (Ramp server)**

For each distinct vendor name, call `ramp-get-bill` with `vendor-name` set to that name and `due-date.to` set to `{due-by}`. Match on invoice number to the FreshBooks bill number, falling back to amount.

**Step 3: Look for payments recorded in FreshBooks**

For any bill where Ramp shows it approved or paid, call `freshbooks-get-bill-payment` with `bill-id` to see whether a payment is already recorded in FreshBooks.

**Step 4: Report**

Table: bill number, vendor, due date, FreshBooks outstanding, Ramp approval status, payment recorded in FreshBooks (yes or no), and an action hint: Not in Ramp, Pending in Ramp, Paid in Ramp but unpaid in FreshBooks, or Unpaid everywhere. Put "Paid in Ramp but unpaid in FreshBooks" first.

**Rules & Guidelines:**

* FreshBooks tools: `freshbooks-get-bill`, `freshbooks-get-vendor`, `freshbooks-get-bill-payment`. Ramp tool: `ramp-get-bill`.
* This prompt is read-only. Do not call `freshbooks-add-bill-payment`, `freshbooks-update-bill-payment` or any other write tool; recording the payment is a separate decision for the user.

**Validation:**

* If no FreshBooks bills qualify, say so and stop.
* If a Ramp bill matches more than one FreshBooks bill, mark it Ambiguous and do not guess.
