feat: adds beforeDocumentControls slot to allow custom component injection next to document controls (#12104)

### What

This PR introduces a new `beforeDocumentControls` slot to the edit view
of both collections and globals.

It allows injecting one or more custom components next to the document
control buttons (e.g., Save, Publish, Save Draft) in the admin UI —
useful for adding context, additional buttons, or custom UI elements.

#### Usage

##### For collections: 

```
admin: {
  components: {
    edit: {
      beforeDocumentControls: ['/path/to/CustomComponent'],
    },
  },
},
```

##### For globals:

```
admin: {
  components: {
    elements: {
      beforeDocumentControls: ['/path/to/CustomComponent'],
    },
  },
},
```

+### beforeDocumentControls
+
+The `beforeDocumentControls` property allows you to render custom components just before the default document action buttons (like Save, Publish, or Preview). This is useful for injecting custom buttons, status indicators, or any other UI elements before the built-in controls.
+
+To add `beforeDocumentControls` components, use the `components.edit.beforeDocumentControls` property in you [Collection Config](../configuration/collections) or `components.elements.beforeDocumentControls` in your [Global Config](../configuration/globals):
+
+#### Collections
+
+```
+export const MyCollection: CollectionConfig = {
+  admin: {
+    components: {
+      edit: {
+        // highlight-start
+        beforeDocumentControls: ['/path/to/CustomComponent'],
+        // highlight-end
+      },
+    },
+  },
+}
+```
+
+#### Globals
+
+```
+export const MyGlobal: GlobalConfig = {
+  admin: {
+    components: {
+      elements: {
+        // highlight-start
+        beforeDocumentControls: ['/path/to/CustomComponent'],
+        // highlight-end
+      },
+    },
+  },
+}
+```
+
+Here's an example of a custom `beforeDocumentControls` component:
+
+#### Server Component
+
+```tsx
+import React from 'react'
+import type { BeforeDocumentControlsServerProps } from 'payload'
+
+export function MyCustomDocumentControlButton(
+  props: BeforeDocumentControlsServerProps,
+) {
+  return <div>This is a custom beforeDocumentControl button (Server)</div>
+}
+```
+
+#### Client Component
+
+```tsx
+'use client'
+import React from 'react'
+import type { BeforeDocumentControlsClientProps } from 'payload'
+
+export function MyCustomDocumentControlButton(
+  props: BeforeDocumentControlsClientProps,
+) {
+  return <div>This is a custom beforeDocumentControl button (Client)</div>
+}
+```
+
 ### SaveDraftButton
 
 The `SaveDraftButton` property allows you to render a custom Save Draft Button in the Edit View.
