fix(application): resolve typecheck errors in estimate-operations tests

- Import EstimateStatus enum instead of using "DRAFT" string literal
- Type BASE_VERSION fixture explicitly so lockedAt accepts Date | null
- Add non-null assertion on mock.calls[0] to satisfy strict types
- Reorder id/spread in version fixture to avoid duplicate property warning
