Show which Pipedrive rep owns each expiring 2Checkout subscriber

**Objective:** Find 2Checkout subscriptions expiring in the next `{days-ahead}` days (default 30) and show which Pipedrive owner and open deals sit behind each subscriber, so the right rep can follow up. Optionally limit to product `{product-name}`.

**Step 1: Find the expiring subscriptions**

Call `2checkout-get-subscription` with `expiration-date.from` set to today, `expiration-date.to` set to today plus `{days-ahead}` days, and `product-name.contains` set to `{product-name}` only when it is not empty. Keep rows whose status is active. Take at most 50 rows. Use `end-user-email`, `subscription-reference`, `product-name` and `expiration-date`.

**Step 2: Look each subscriber up in Pipedrive**

For each subscription with a non-blank `end-user-email`, call `pipedrive-get-person` with `email` set to it. Record owner-name, organization-name and open-deals. If nothing returns, mark the subscriber as not in Pipedrive.

**Step 3: Report**

Table sorted by expiration-date: subscription-reference, product-name, expiration-date, end-user-email, Pipedrive owner-name, open-deals. Then group counts by owner and list the subscribers with no Pipedrive person or no email.

**Rules & Guidelines:**

* `2checkout-*` tools belong to the 2checkout server and `pipedrive-*` tools to the pipedrive server; both servers must be connected.
* This prompt is read-only. Never call any 2checkout write tool (for example `2checkout-customer-add`, `2checkout-customer-update`, `2checkout-subscription-disable`) or any pipedrive write tool (`pipedrive-add-person`, `pipedrive-update-person`, `pipedrive-add-deal`, `pipedrive-update-deal`, `pipedrive-add-note`, `pipedrive-add-activity`).
* Match emails case-insensitively after trimming spaces; never alter the stored value in the report.

**Validation:**

* If no subscriptions expire in the window, say so and stop.
* Report blank emails instead of guessing a match.
