### What?
If you have a custom field that sets the value of the field using the
`useField` hook on entry into a document - the `updatedAt` field would
be updated even when a non-owner tries to enter a locked document.
### Why?
When a field is updated in the edit view - we perform an update in
`form-state` to keep the doc in `payload-locked-documents` up to date
with the current editing status. The above scenario would hit this
update operation even on non-owner users because it was previously only
checking for `updateLastEdited` (which would get hit by the `setValue`
in the `useField` hook) so we also need to check to make sure the
current user entering a locked doc is also the owner of the document.
### How?
When performing an update to `payload-locked-documents` in
`buildFormState` - only perform the update if the current user is also
the owner of the locked document otherwise skip the `update` operation.
Fixes#8781
### What?
When read access is restricted on the `users` collection - restricted
users would not have access to other users complete user data object
only their IDs when accessing `user.value`.
### Why?
This is problematic when determining the lock status of a document from
a restricted users perspective as `user.id` would not exist - the user
data would not be an object in this case but instead a `string` or
`number` value for user ID
### How?
This PR properly handles both cases now and checks if the incoming user
data is an object or just a `string` / `number`.
## Description
Adds a new property to `collection` / `global` configs called
`lockDocuments`.
Set to `true` by default - the lock is automatically triggered when a
user begins editing a document within the Admin Panel and remains in
place until the user exits the editing view or the lock expires due to
inactivity.
Set to `false` to disable document locking entirely - i.e.
`lockDocuments: false`
You can pass an object to this property to configure the `duration` in
seconds, which defines how long the document remains locked without user
interaction. If no edits are made within the specified time (default:
300 seconds), the lock expires, allowing other users to edit / update or
delete the document.
```
lockDocuments: {
duration: 180, // 180 seconds or 3 minutes
}
```
