Disable number grouping (thousands comma separators) by default in Vue node number widgets (#5776)

## Summary

Makes the
[useGrouping](https://primevue.org/inputnumber/#api.inputnumber.props.useGrouping)
prop for number widgets disabled by default, aligning with the old UI
(also requested via design). Node authors can still enable if they want
by setting prop explicitly.

## Changes

- **What**: Modified
[WidgetInputNumberInput](https://primevue.org/inputnumber/) to disable
`useGrouping` by default, requiring explicit opt-in via widget options
- **Testing**: Added component tests covering value binding, component
rendering, step calculations, and grouping behavior

## Review Focus

UX impact on existing nodes that may have relied on default grouping
behavior and test coverage for edge cases with precision calculations.
