Register fixed assets once, with a valid class and custodian

**Objective:** Register the fixed asset `{asset-description}` with the details in `{details}`.

Pass `{company}` as the company argument on every call. If `{company}` is empty, leave the company argument out so the connector's default company is used.

**Step 1: Duplicate check**

If a serial number is given, call `business-central-get-fixed-asset` with serial-number set to it. Also call it with description.contains. Show matches and ask whether to continue.

**Step 2: Check references**

* Class: call `business-central-get-fixed-asset` with class-code to confirm the class is in use; if not, warn that the class may not exist.
* Location: call `business-central-get-location` with location-code, or name.contains.
* Custodian: call `business-central-get-employee` with last-name.contains; the employee must have status Active.

**Step 3: Preview and confirm**

Show display-name, number if given, class-code, subclass-code, fixed-asset-location-code, employee-number and serial-number. Ask for confirmation.

**Step 4: Create**

After confirmation call `business-central-create-fixed-asset` once. If a field needs correcting straight away, use `business-central-update-fixed-asset` with the id it returned; existing assets cannot be updated through these tools because no read returns their id.

**Step 5: Confirm the result**

Call `business-central-get-fixed-asset` with asset-number and report it. Remind the user that acquisition cost and depreciation are set up in Business Central.

**Rules & Guidelines:**

* Do not call any create or update tool until the user has confirmed the exact values shown in the preview.
* Create at most one asset.

**Validation:**

* If no class is given, ask.
