… string based id (#4331)

This feature allows developers to use a function or a React Context as
the reference instead of a string-based ID. This can be useful for
ensuring a safe local scope, especially when multiple form handlers are
present.

```tsx
const myReference= () => null

const MyField = () => {
  const { data } = Form.useData(myReference)
  return data.foo
} 

render(
<>
  <Form.Handler id={myReference}>
    ...
  </Form.Handler>
  
  <MyField />
</>
)
```

Fixes a missing commit for PR #4332

… file list rendering (#4339)

When using `sessionStorageId` on `Form.Handler` alongside `Field.Upload`
with a specified path, file data is stored. However, during
serialization, Blob information is not preserved in session storage. As
a result, reading this data causes `Field.Upload` to throw an exception.

This PR ensures invalid files are not rendered, preventing such errors.

In the future, we could explore storing Blobs in IndexedDB, but that
would require a more extensive effort.

…ry codes (#4340)

Fixes #4337

* Also fixed not scrolling to current page when opening menu on small
screens

…pt types (#4343)

The main change is that we go from:

```tsx
type JsonObject = any
```

to

```tsx
type JsonObject = Record<string | number, unknown> | Array<unknown>
```

and enhance the TypeScript support docs for the "Getting Started"
section the `Form.Handler` and `Form.Isolation` docs.

To disable types you can do so by:


```tsx
<Form.Handler<any>>
...
</Form.Handler>
```

or

```tsx
const { data } = Form.useData<any>()
```

…ops that have changed (#4342)

- [x] Add test
- [x] FIx same issue in `range` mode
- [x] Update failing `Field.Date` test
- [x] Clean up `updateBasedOnProps` code


Should hopefully fix the issue described
[here](https://dnb-it.slack.com/archives/CMXABCHEY/p1732031524606929)

Neither of us were able to recreate the issue in csb, so testing this
manually might be a challenge

This also improves input deletion behaviour when the dates are prop
controlled
