Abdullah. c7919673af fix: lift root postcss to 8.5.23 (Dependabot) (#23396)
## Summary

Clears the root postcss alert
[1851](https://github.com/twentyhq/twenty/security/dependabot/1851):
**GHSA-r28c-9q8g-f849** (high) - path traversal in previous source map
auto-loading (`sourceMappingURL`) leading to arbitrary `.map` file
disclosure, vulnerable `<= 8.5.17`.

The root lockfile carried **two** vulnerable copies, both behind exact
pins with no fixed upstream release:

| Copy | Pinner | Latest release still pins |
|---|---|---|
| 8.5.15 | `next` (8.4.31 exact) | 16.2.12 -> 8.4.31 |
| 8.5.14 | `@mintlify/common` (8.5.14 exact) | 1.0.1051 -> 8.5.14 |

So no parent upgrade reaches the fix. The existing `next/postcss`
resolution moves **8.5.15 -> 8.5.23** and a matching
**`@mintlify/common/postcss`** pin is added, placed alphabetically among
the other `@mintlify/*` entries. The caret consumers (`^8.4.38`,
`^8.4.47`, `^8.5.15`) dedupe onto the same version.

## Verification

- The two copies **collapse into a single `postcss@8.5.23` entry**;
nothing at or below 8.5.17 remains.
- `yarn install --immutable` passes.
- 8.5.23 published 2026-07-24, clears the 3-day npm age gate.
- `//resolutions` updated with the advisory, both pinners (and their
latest-version evidence) and the drop condition.

The app-lockfile side of this advisory shipped separately in #23340.
