Show fundraisers which donors clicked your Mailchimp appeal

**Objective:** For the Mailchimp campaign `{campaign-title}`, log one DonorPerfect contact record with activity code `{activity-code}` against each donor who clicked a link in it.

**Step 1: Validate the activity code**

Call `donorperfect-get-code` with `code` set to `{activity-code}`. Confirm a match whose field name is the contact activity code field and that is not inactive. If there is no match, list nearby codes with `description.contains` and stop.

**Step 2: Find the campaign and its clickers**

Call `mailchimp-get-campaign` with `title.contains` set to `{campaign-title}`. If there is not exactly one match, list them and stop. Note `campaign-id`, `title` and `send-date`. Call `mailchimp-get-campaign-email-activity` with that `campaign-id` and `action` set to click. De-duplicate by email, keeping the first click date and the URLs clicked.

**Step 3: Match to donors and skip duplicates**

For each email, call `donorperfect-get-donor` with `email` (fall back to `donorperfect-get-address` with `email`). For each matched donor, call `donorperfect-get-contact` with `donor-id` and `activity-code` set to `{activity-code}` and `contact-date.from` set to the send date; skip any donor who already has one, so re-running is safe.

**Step 4: Confirm before writing**

Show the donors to log (donor id, name, email, first click date) and the unmatched email count. Ask the user to confirm. Do not write until they do.

**Step 5: Log the contacts**

For each confirmed donor, call `donorperfect-save-contact` with `donor-id`, `activity-code` set to `{activity-code}`, `contact-date` set to the first click date, `completed-date` set to the same date, and `comment` set to "Clicked Mailchimp campaign: <title>" followed by the clicked URLs. Leave `contact-id` empty so a new record is created. Record any failure and continue.

**Step 6: Report**

Logged, skipped as already logged, failed, and unmatched counts, with the logged rows.

**Rules & Guidelines:**

* `mailchimp-get-campaign` and `mailchimp-get-campaign-email-activity` are on the mailchimp server. `donorperfect-get-code`, `donorperfect-get-donor`, `donorperfect-get-address`, `donorperfect-get-contact` and `donorperfect-save-contact` are on the donorperfect server.
* `donorperfect-save-contact` is the only write, only after Step 4 confirmation. Do NOT call `donorperfect-save-donor`, `donorperfect-set-flag` or any Mailchimp action tool.

**Validation:**

* If the campaign has no clicks, say so and stop.
* Never pass a `contact-id`: that would overwrite an existing contact record.
