Update realtime compiler dashboard configuration schema

[caendesilva]

This moves the dashboard settings into an array. While this is a somewhat intrusive change, requiring user intervention due to the implicit deprecation, it helps make the configuration file cleaner by grouping semantically related elements. An added check makes sure to provide backwards compatibility with older configuration options.

The shortened editor/tips keys are not breaking, as they have not been released yet.

To upgrade, replace the following in config/hyde.php:

'server' => [
    // ...

    'enabled' => env('SERVER_DASHBOARD', true),
],

With this:

'server' => [
    // ...

    'dashboard' => [
        'enabled' => env('SERVER_DASHBOARD', true),
    ],
],
