Fix the default value of search record if the filter is boolean type (#17297)

This fixes the #15896. For problem statement. Please refer to the shared
video mentioned in the issue.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Aligns filter defaults across UI by centralizing initial value
computation.
> 
> - Add boolean handling in `useGetInitialFilterValue` to return
`value/displayValue` of `'false'` when operand is `IS`
> - Update `WorkflowDropdownStepOutputItems` to use
`getInitialFilterValue` for initial `value` instead of an empty string,
based on field type and default operand
