fix: ensure req.query is writable (#81573)
### What?
- Upgrade development dependency **Express** to the latest version
(5.1.0).
- Replace direct assignment of `apiReq.query` with
`Object.defineProperty` to ensure the property is writable, enumerable,
and configurable.
### Why?
- To use the most up-to-date and supported version of Express instead of
a legacy one.
- To fix
[expressjs/express#6633](https://github.com/expressjs/express/issues/6633),
where Express 5.x defines `req.query` as a read-only getter, preventing
Next.js from overriding it directly.
### How?
- Update the Express version in `package.json` and run `pnpm install` to
apply the change.
- Replace:
```js
apiReq.query = query;
```
With
```js
Object.defineProperty(apiReq, 'query', {
value: { ...query },
writable: true,
enumerable: true,
configurable: true,
});
```
