fix(security): drop vulnerable serialize-javascript via terser-webpack-plugin bump (#21871)

## fix(security): drop vulnerable serialize-javascript via
terser-webpack-plugin bump

Resolves [Dependabot Alert
#548](https://github.com/twentyhq/twenty/security/dependabot/548) and
[#1290](https://github.com/twentyhq/twenty/security/dependabot/1290).

### What

`serialize-javascript` `< 7.0.5` is affected by:
- **RCE via `RegExp.flags` / `Date.prototype.toISOString`**
([#548](https://github.com/twentyhq/twenty/security/dependabot/548),
High)
- **CPU-exhaustion DoS via crafted array-like objects**
([#1290](https://github.com/twentyhq/twenty/security/dependabot/1290),
Moderate)

### How — parent-bump, no resolution

The only consumer of the vulnerable `serialize-javascript@^6.0.2` in the
tree was `terser-webpack-plugin`, which **removed the
`serialize-javascript` dependency in 5.4.0**. This bumps
`terser-webpack-plugin` `5.3.16 -> 5.6.1` within its existing `^5.3.16`
range — an in-range parent-bump that drops `serialize-javascript` from
the tree **entirely** (preferred over a `resolutions` override).

### Verification

- `serialize-javascript` no longer resolves anywhere in the tree (both
the vulnerable `6.0.2` and the prior `7.0.5` copies are gone).
- `terser-webpack-plugin` is dev/build tooling (webpack minification),
not imported in our source.
- Lockfile-only change (net −22 lines); `yarn install --immutable`
passes.
