Charles Bochet 6af06c1062 security: postcss CVE via styled-components bump + next/postcss resolution (Dependabot alert 1061) (#21438)
Closes the postcss Dependabot alert —
[1061](https://github.com/twentyhq/twenty/security/dependabot/1061) — by
**bumping one parent** and using a **scoped resolution** only where
there's no other path.

postcss `< 8.5.10` (XSS via unescaped `</style>` in stringify output)
was bundled by two parents:

### styled-components → bumped (no resolution)
`styled-components 6.4.2` (in-range for our `^6.1.0`; we were on a stale
6.3.12) **dropped its postcss dependency entirely**, so a plain `yarn
up` removes the 8.4.49 copy — no override. (styled-components is only
used in one component-renderer Storybook showcase; product UI is on
Linaria.) Re-built `twenty-front-component-renderer` to confirm the
bump.

### next → scoped resolution (no parent path)
`next` pins postcss `8.4.31` **exact on every stable release** —
next@latest (16.2.9) still pins it; the fix (8.5.10) exists only in the
**16.3.0 canary** (unreleased). So `next/postcss: 8.5.15` is the only
mechanism, scoped to next and documented in the top-level
`//resolutions` note with a removal trigger.

### Verification
- Every postcss now resolves `>= 8.5.14` (safe); `yarn install
--immutable` ✓.
- postcss is build-time and **CI doesn't build twenty-website on regular
PRs**, so verified locally: **twenty-website** (Next production build) ✓
and **twenty-front-component-renderer** ✓.
