security: bump path-to-regexp and defu to patched versions (lockfile refresh) (#21369)

## What

Clears two **High** Dependabot alerts
(https://github.com/twentyhq/twenty/security/dependabot) from the root
tree **without resolutions/overrides** — by refreshing the lockfile so
the existing semver ranges pick up the already-patched releases.

| Package | From → To | Requested by | Advisory |
|---|---|---|---|
| path-to-regexp | 8.3.0 → 8.4.2 | `router` (`^8.0.0`) |
GHSA-j3q9-mxjg-w52f |
| defu | 6.1.4 → 6.1.7 | `radix-vue` (`^6.1.4`) | GHSA-737v-mqg7-c878 |

Only `yarn.lock` changes — no `package.json` edits, no `resolutions`.

## Why only these two

I traced every vulnerable transitive back to its parent. Only `defu` and
`path-to-regexp` were stuck purely on a stale lockfile (their parents'
ranges already allow the patched version). The remaining root High
alerts can **not** be fixed by a parent update:

- **next** — latest `@react-email/preview-server` (5.2.10) still ships
`next@16.1.7`, itself vulnerable
- **immutable** — `@ardatan/relay-compiler@12.0.0` is terminal and pins
`~3.7.6`
- **minimatch / lodash / ws** — exact-pinned deep in dev tooling
(api-extractor, spectral, NestJS, graphql-tools) with no fixed upstream
release

Those will be handled separately.

## Verification

- `nx typecheck` passes for twenty-server and twenty-front

yarn.lock
