See a donor's TickTick tasks beside their DonorPerfect history

**Objective:** Find every TickTick task about the DonorPerfect donor `{donor}` and show it next to the donor's giving and contact history. Look at tasks due within `{days}` days (default 30, use all open tasks if the user asks for everything).

**Step 1: Identify the donor (DonorPerfect)**

If `{donor}` is all digits, call `donorperfect-get-donor` with `donor-id` set to it. Otherwise call `donorperfect-get-donor` with `last-name.contains` (or `last-name` if the user gave an exact name). If more than one donor matches, list them with donor-id, name, city and email and stop so the user can pick.

**Step 2: Find the tasks (TickTick)**

TickTick has no donor field, so the join is text. Call `ticktick-get-tasks` with `title.contains` set to the donor's last name (or organization-name), `status` open, and `due-date.to` set to today plus `{days}` days. Run it a second time with `title.contains` set to the donor-id and merge the results by `id`. Discard tasks that clearly name a different person with the same surname.

**Step 3: Add context (DonorPerfect)**

Call `donorperfect-get-contact` with the donor-id and keep the 3 most recent contacts. Call `donorperfect-get-gift` with the donor-id and keep the 3 most recent gifts.

**Step 4: Report**

Donor header: donor-id, name, gift-total, year-to-date, last-contribution-amount. Then a table of tasks: title, project-name, due-date, priority, tags. Then the last contacts and gifts. Flag any task that is overdue.

**Rules & Guidelines:**

* `ticktick-get-tasks` is on the TickTick server; `donorperfect-get-donor`, `donorperfect-get-contact` and `donorperfect-get-gift` are on the DonorPerfect server.
* Read only. Never call any of: `ticktick-add-task`, `ticktick-update-task`, `ticktick-complete-task`, `ticktick-delete-task`, `ticktick-batch-tasks`, `ticktick-move-task`, `ticktick-add-comment`, `donorperfect-save-donor`, `donorperfect-save-gift`, `donorperfect-save-pledge`, `donorperfect-save-contact`, `donorperfect-save-address`, `donorperfect-save-link`, `donorperfect-set-flag`, `donorperfect-save-other-info`.

**Validation:**

* If no task matches, say the donor has no TickTick tasks and still report the DonorPerfect history.
* If the donor is not found in DonorPerfect, say so and list the TickTick tasks that matched the text you searched for.
