Assign expiring 2Checkout renewals to the right HubSpot owner

**Objective:** Find 2Checkout subscriptions that expire between `{from-date}` and `{to-date}` (dates as yyyy-mm-dd) and show, for each, who owns the customer in HubSpot and whether a deal is already open, so renewals can be assigned.

**Step 1: Read expiring subscriptions from 2Checkout**

Call `2checkout-get-subscription` with `expiration-date.from` set to `{from-date}`, `expiration-date.to` set to `{to-date}` and `max-records` set to `{max-records}` (25 if empty). Keep `subscription-reference`, `product-name`, `status`, `expiration-date` and `end-user-email`. Skip subscriptions with no email and count them.

**Step 2: Find the owner and open deals in HubSpot**

For each distinct `end-user-email`, call `hubspot-get-contacts` with `email` set to it. Keep `record-id`, `company-id`, `contact-owner` and `lifecycle-stage`. If a company id is present, call `hubspot-get-deals` with `company-id` set to it and keep `deal-name`, `deal-stage-name`, `amount` and `close-date`. If no contact comes back, mark the subscription as having no CRM owner.

**Step 3: Report**

Give a table sorted by `expiration-date`: customer email, product, expiry, HubSpot owner, lifecycle stage and open deals. Then list the subscriptions with no CRM owner separately, because nobody is following up on them.

**Rules & Guidelines:**

* Tools whose names start with 2checkout belong to the 2checkout server and tools whose names start with hubspot belong to the HubSpot server. Both servers must be connected.
* The shared key is the email address: 2checkout `email` / `end-user-email` against HubSpot `email`. Compare emails case-insensitively after trimming spaces.
* This is read-only. Never call any 2checkout action tool (any 2checkout tool that adds, updates, cancels, refunds, enables, disables, renews or extends) and never call `hubspot-add-contact`, `hubspot-update-contact`, `hubspot-add-company`, `hubspot-update-company`, `hubspot-add-deal`, `hubspot-update-deal`, `hubspot-add-deal-note`, `hubspot-add-contact-note`, `hubspot-add-company-note`, `hubspot-add-ticket`, `hubspot-update-ticket` or `hubspot-add-ticket-note`.

**Validation:**

* If either date is missing or not a valid date, ask for it and stop.
* If no subscription expires in the window, say so and stop.
* Do not guess an owner when several contacts share an email; list them.
