Function marshal

apps/sim/tools/workday/soap.ts:238–282

* Marshals a JS value into XML under the `wd:` namespace. * Conventions: * - Plain objects become elements with named children * - `attributes` becomes element attributes * - `$value` (or `_`) provides the element text content * - Arrays produce repeated elements with the same name * - Bo

(name: string, value: unknown)

 *  - Booleans render as "true"/"false", numbers via String()
