Remove all styled(Component) patterns in favor of parent wrappers and props (#18430)
## Summary
Eliminates all ~350 `styled(Component)` usages across `twenty-front` and
`twenty-ui` (212 files changed). Each was replaced following these
rules:
- **Margin/layout CSS** (margin, padding, flex, align-self, width) →
wrapped in a `styled.div`/`styled.span` parent container
- **Third-party components** (Link, TextareaAutosize,
ReactPhoneNumberInput, Handle, etc.) → parent container with child CSS
selectors (`> a`, `> textarea`, `> input`, etc.)
- **Intrinsic behavior via existing props** (TableRow
`gridTemplateColumns`, TableCell `color`/`align`) → replaced
`styled(TableRow)` / `styled(TableCell)` with direct prop usage
- **Other visual overrides on twenty-ui components** (Card, Section,
TabList, Button, MenuItem, ScrollWrapper, etc.) → parent wrappers with
`> div` / `> *` child selectors
- **Extending styled.div/span** → merged all CSS into a single
`styled.div`/`styled.span`
Also adds `overflow: hidden` to parent containers wrapping
`ScrollWrapper` so scroll activates correctly with the new wrapper
structure.
