Hold follow-ups for campaign engagers with open Freshdesk tickets

**Objective:** For campaign `{campaign-id}`, find the contacts who opened or clicked it and who also have unresolved tickets in Freshdesk. Return at most `{max-contacts}` contacts (default 25).

**Step 1: Get the engaged contacts (Constant Contact server)**

Call `constant-contact-get-campaign` with `campaign-id` set to `{campaign-id}` to confirm the campaign exists and note its name. If it does not exist, stop. Then call `constant-contact-get-campaign-click` and `constant-contact-get-campaign-open` with `campaign-id`, each limited to `{max-contacts}` records. Combine them into one list of unique `email-address` values and note whether each clicked, opened, or both.

**Step 2: Check support status (Freshdesk server)**

For each email, call `freshdesk-get-tickets` with `requester-email` set to that email. Keep only tickets whose status is not resolved or closed.

**Step 3: Report**

A table of email, engagement (clicked / opened), open ticket count, and the newest open ticket subject and priority. List contacts with no open tickets only as a count. Say how many contacts were checked.

**Rules & Guidelines:**

* The campaign tools are on the Constant Contact server; `freshdesk-get-tickets` is on the Freshdesk server.
* This is read-only. Do not call any add, update, delete, reply or resend tool on either server, including `constant-contact-resend-campaign-to-non-openers` and `freshdesk-add-ticket-note`.

**Validation:**

* If a campaign has no opens or clicks, say so and stop.
* If an email has no Freshdesk tickets at all, treat it as no open tickets.
