Function sapObjectLock

sapObjectLock(objectType: string, objectKey: string): string
Builds a lock name scoped to one SAP business object.
Parameters
- objectType: string
  Business object type, e.g. 'PurchaseOrder'.
- objectKey: string
  The instance key, e.g. '4500000123'.
Returns string
A lock name of the form sap:sm12:<objectType>:<objectKey>.
Remarks
Named after SM12, the SAP lock-entry transaction, because this is the client-side counterpart: it stops two workers reaching the same object at once, rather than reporting the collision after the fact.

Scoped deliberately — two tests editing different purchase orders should still run in parallel, which a single blanket sap:purchase-order lock would prevent.

Throws
PramanError with ERR_CONFIG_INVALID when either part is blank.
Example
```
import { sapObjectLock } from 'playwright-praman';

const lock = sapObjectLock('PurchaseOrder', '4500000123');
// 'sap:sm12:PurchaseOrder:4500000123'

test('approves the PO', { lock }, async ({ ui5 }) => { ... });
```
