See everything about a Geotab device in one answer

**Objective:** Build a complete profile of device `{device-serial}`: its contract, plan, database, sharing, add-in enrolment, pending plan changes and this month's billing.

**Step 1: Find the contract**

Call `geotab-myadmin-get-device-contract` with device-serial = {device-serial}. If nothing comes back, say the serial was not found under this account and stop. Note the account, device plan, device type, start and end dates, terminated flag and VIN.

**Step 2: Where the device lives**

* Call `geotab-myadmin-get-current-device-database` with device-serial = {device-serial} for the database it reports to now.
* Call `geotab-myadmin-get-device-database-name` with device-serial = {device-serial} for the owner database and any shared databases.

**Step 3: Add-ins and plan changes**

* Call `geotab-myadmin-get-device-add-in-detail` with device-serial = {device-serial} for add-in enrolment, plan and monthly fee.
* Call `geotab-myadmin-get-device-contract-auto-request` with device-serial = {device-serial} for scheduled or failed plan changes.
* Call `geotab-myadmin-get-device-add-in-audit-log` with device-serial = {device-serial} for recent enrol and unenrol actions.

**Step 4: This month's billing**

Call `geotab-myadmin-get-device-contract-transaction` with device-serial = {device-serial} (current month by default) and `geotab-myadmin-get-device-contract-credit-transaction` with the same serial.

**Step 5: Report**

A short header (serial, VIN, device type, account, database), then sections: Contract, Databases and sharing, Add-ins, Pending changes, Billing this month (charges, credits, net). End with any red flags: terminated but still billed, failed auto-requests, database mismatch between contract and current database.

**Rules & Guidelines:**

* This is a read-only job. Do NOT call any write tool: no `geotab-myadmin-change-device-billing-plan`, `geotab-myadmin-terminate-device-billing`, `geotab-myadmin-share-device`, `geotab-myadmin-update-device-contracts`, `geotab-myadmin-enroll-device-from-add-in`, `geotab-myadmin-unenroll-device-from-add-in` or any other action tool.
* Report values as returned; do not guess missing ones.

**Validation:**

* If a section returns nothing, write "none found" for it rather than omitting it.
