Adds a new operation findDistinct that can give you distinct values of a field for a given collection
Example:
Assume you have a collection posts with multiple documents, and some of them share the same title:

// Example dataset (some titles appear multiple times)
[
  { title: 'title-1' },
  { title: 'title-2' },
  { title: 'title-1' },
  { title: 'title-3' },
  { title: 'title-2' },
  { title: 'title-4' },
  { title: 'title-5' },
  { title: 'title-6' },
  { title: 'title-7' },
  { title: 'title-8' },
  { title: 'title-9' },
]

You can now retrieve all unique title values using findDistinct:

const result = await payload.findDistinct({
  collection: 'posts',
  field: 'title',
})

console.log(result.values)
// Output:
// [
//   'title-1',
//   'title-2',
//   'title-3',
//   'title-4',
//   'title-5',
//   'title-6',
//   'title-7',
//   'title-8',
//   'title-9'
// ]

You can also limit the number of distinct results:

const limitedResult = await payload.findDistinct({
  collection: 'posts',
  field: 'title',
  sortOrder: 'desc',
  limit: 3,
})

console.log(limitedResult.values)
// Output:
// [
//   'title-1',
//   'title-2',
//   'title-3'
// ]

You can also pass a where query to filter the documents.

Shouldn't this have updates to the REST and GraphQL docs?

For now the REST API endpoint is disabled and there's no GraphQL. I was thinking that we might not need that

Supports grouping documents by specific fields within the list view.

For example, imagine having a "posts" collection with a "categories"
field. To report on each specific category, you'd traditionally filter
for each category, one at a time. This can be quite inefficient,
especially with large datasets.

Now, you can interact with all categories simultaneously, grouped by
distinct values.

Here is a simple demonstration:


https://github.com/user-attachments/assets/0dcd19d2-e983-47e6-9ea2-cfdd2424d8b5

Enable on any collection by setting the `admin.groupBy` property:

```ts
import type { CollectionConfig } from 'payload'

const MyCollection: CollectionConfig = {
  // ...
  admin: {
    groupBy: true
  }
}
```

This is currently marked as beta to gather feedback while we reach full
stability, and to leave room for API changes and other modifications.
Use at your own risk.

Note: when using `groupBy`, bulk editing is done group-by-group. In the
future we may support cross-group bulk editing.

Dependent on #13102 (merged).

…irtual fields (#14026)

This adds support for using `findDistinct`
#13102 on fields:
* Nested to a relationship, for example `category.title`
* Virtual fields that are linked to relationships, for example
`categoryTitle`


```tsx
const Category: CollectionConfig = {
  slug: 'categories',
  fields: [
    {
      name: 'title',
      type: 'text',
    },
  ],
}

const Posts: CollectionConfig = {
  slug: 'posts',
  fields: [
    {
      name: 'category',
      type: 'relationship',
      relationTo: 'categories',
    },
    {
      name: 'categoryTitle',
      type: 'text',
      virtual: 'category.title',
    },
  ],
}

// Supported now
const relationResult = await payload.findDistinct({ collection: 'posts', field: 'category.title' })
// Supported now
const virtualResult = await payload.findDistinct({ collection: 'posts', field: 'categoryTitle' })
```
