Handle child FormWidgets making AJAX requests outside of the repeater's form container. Note that this won't pass on the state of the repeater item as it exists on the webpage because that information won't be sent to the server in an AJAX request sent from outside of the repeater's form container unless the FormWidget sending the orphaned request specifically includes that data in their request, in which case the regular handling will kick in and initialize the widget properly. A discussion should be had whether this fix makes sense to be done in the Repeater FormWidget or if we should force FormWidgets to have the responsibility of initializing their parent repeaters if they're going to be making orphaned AJAX requests.
Should fix#3415, #4672.

Added getConfig to make it easier for developers to fetch the config data from a list column while overriding the list items through extension. This also makes the class more compatible with [FormField](https://github.com/octobercms/october/blob/master/modules/backend/classes/FormField.php) which already has the same helper function.
Also had to revert the 100vw improvement on tabs because it causes unnecessary scroll/drag activation. Also reverted change in form.base.less that had no reasoning.
It makes more sense to use a consistent UI for all modes, the CSS is cleaner as a result. The code editor toolbar has been moved to the bottom across all instances. This is favourable to it bleeding outside of its perimeter.

This change will allow the individual JS assets that are compiled into a full compilation file to be loaded individually instead, allowing the developer to see their changes immediately. It introduces a new configuration variable, `cms.decompileBackendAssets`, that controls this functionality. By default, it is false and not tied to the debug value, requiring it to be explicitly enabled.
An exception was thrown when loading middleware if a requested controller is from a disabled plugin, as the `getRequestedController` method returns a Response object in this scenario.
Hat tip to @w20k.
This will detect invalid navigation item configuration in installed plugins. In debug mode, this will throw an error, otherwise, it will simply log the error.
