fix(workday): coerce compensation amounts and guard Date marshaling

- get-compensation returned Amount/Per_Unit_Amount/Individual_Target_Amount
  as strings (XML leaf text), violating the tool's number contract
- Coerce via parseSoapNumber and widen plan type to number | string
- Add defensive Date branch in marshal() so Date inputs serialize as
  ISO 8601 instead of String(date)
