## Summary
- Add Storybook stories for WidgetInputText, WidgetTextarea, and
ScrubableNumberInput
- Reorganize story titles under `Components/Input/` to align with Figma
design system
- Fix PrimeIcons not rendering in Storybook (caused by
`[&_*]:!font-inter` override)
- Fix knip unused export warnings (dead code removal + workspace config)

## Test plan
- [ ] Run `pnpm storybook` and verify Components/Input/InputText stories
render
- [ ] Verify Components/Input/TextArea stories render with label and
copy button
- [ ] Verify Components/Input/Number stories render with -/+ icons
- [ ] Toggle Storybook theme between Light/Dark and confirm Number story
adapts
- [ ] Verify existing Button stories still render correctly
