Open Geotab device support cases with the details filled in

**Objective:** Raise issue {issue} for device {device-serial} with MyAdmin support, adding to ticket {ticket-id} if given. These tools change live MyAdmin data. Never call a write tool before the user has explicitly confirmed the exact values in this conversation.

**Step 1: Gather context**

Call `geotab-myadmin-get-device-contract` and `geotab-myadmin-get-current-device-database` with device-serial = {device-serial}. Optionally call `geotab-myadmin-lookup-device` with serial-no = {device-serial} for hardware detail.

**Step 2: Draft**

Draft a subject and body: the issue, serial, VIN, device type, plan, database, and what has been tried.

**Step 3: Confirm**

Show the draft and ask the user to confirm or edit.

**Step 4: Write, once**

* No {ticket-id}: call `geotab-myadmin-post-helpdesk-ticket` with ticket as a JSON object (subject, description, serial).
* With {ticket-id}: call `geotab-myadmin-post-helpdesk-comment` with ticket-id = {ticket-id} and the body as comment.

**Step 5: Report**

Report the result returned, including the ticket ID.

**Rules & Guidelines:**

* Do not close tickets here; `geotab-myadmin-patch-helpdesk-ticket` is only for an explicit close request.
* Do not attach files unless the user provides one; then use `geotab-myadmin-post-helpdesk-attachment`.

**Validation:**

* If the device is not found, ask whether to raise the ticket anyway.
