[wrangler] sortObjectRecursive throws TypeError on null inside an array

### What versions & operating system are you using?

Wrangler 4.114.0, Node v24.11.0, macOS 15 (Darwin 24.6.0). Also present on `main` @ `3a141ed11`.

### Please provide a link to a minimal reproduction

No repo needed — the reproduction is a two-line call against the exported helper, included below.

### Describe the Bug

`sortObjectRecursive()` throws a `TypeError` when the object it is given contains an array with `null` in it.

The function guards against `null` for **object properties**, but not for **array elements**:

```ts
// packages/wrangler/src/utils/sortObjectRecursive.ts
if (Array.isArray(object)) {
return object.map((obj) => sortObjectRecursive(obj)) as T; // <-- null passed straight through
}

const objectCopy = { ...object };
for (const [key, value] of Object.entries(object)) {
if (typeof value === "object") {
if (value === null) { continue; } // <-- only protects direct properties
...
```

When a `null` array element is recursed into, `typeof null === "object"` passes the early return, `Array.isArray(null)` is false, and execution reaches `Object.entries(null)`, which throws.

Reproduction:

```js
sortObjectRecursive({ a: [null] });
// TypeError: Cannot convert undefined or null to object
```

**Expected:** `null` is preserved in place, i.e. `{ a: [null] }`, consistent with how `null` is already handled for object properties.

**Why it matters:** this helper normalises objects so they can be diffed and rendered. It is used on user-supplied configuration in the cloudchamber/containers commands (`sortObjectRecursive` feeds the config-diff rendering), so any config containing an array with a `null` entry crashes the command rather than showing a diff. JSON configs legitimately contain `null` inside arrays.

### Please provide any relevant error logs

```
TypeError: Cannot convert undefined or null to object
at Function.entries ()
at sortObjectRecursive (packages/wrangler/src/utils/sortObjectRecursive.ts)
```

Start in packages/wrangler/src/utils/sortObjectRecursive.ts and run the two-line sortObjectRecursive({ a: [null] }) reproduction. Confirm that null array elements are preserved and the helper no longer throws while normalizing the configuration for diff rendering.
