fix(security): bump protobufjs to 7.6.4 (DoS + property shadowing) (#21811)

## fix(security): bump protobufjs to 7.6.4 (DoS + property shadowing)

Resolves [Dependabot Alert
#1508](https://github.com/twentyhq/twenty/security/dependabot/1508) and
[#1507](https://github.com/twentyhq/twenty/security/dependabot/1507).

### What

`protobufjs` in the 7.x line is affected by two advisories:
-
[GHSA-wcpc-wj8m-hjx6](https://github.com/advisories/GHSA-wcpc-wj8m-hjx6)
(**High**,
[#1508](https://github.com/twentyhq/twenty/security/dependabot/1508)) —
DoS through unbounded `Any` expansion during JSON conversion. Patched in
`7.6.1`.
-
[GHSA-f38q-mgvj-vph7](https://github.com/advisories/GHSA-f38q-mgvj-vph7)
(**Moderate**,
[#1507](https://github.com/twentyhq/twenty/security/dependabot/1507)) —
schema-derived names can shadow runtime-significant properties. Patched
in `7.6.3`.

### How

`protobufjs` is pulled transitively via `^7.3.0`, which already permits
the patched releases. This refreshes the stale lockfile resolution
`7.6.0 → 7.6.4` (the latest `7.x`; `>= 7.6.3` covers both advisories)
within the existing range — no `resolutions` override needed. The `8.x`
ranges in these advisories do not apply.

### Verification

- `protobufjs` resolves to a single `7.6.4` bucket (`>= 7.6.1` and `>=
7.6.3`), clearing both alerts.
- Diff is limited to the protobufjs family (`protobufjs` + its
`@protobufjs/*` utility deps).
- Lockfile-only change; `yarn install --immutable` passes.
