Correct Public URL for the custom Logo in settings and in estimations headers

[tkapias]

In the current master the custom Logo picture is forced with the localhost URL from the APP_URL env variable.

I use it behind a proxy and a public URL, here my own correction :

webroot/.env

• Add a new variable with the custom public URL :

WEB_URL=https://public.domain

webroot/config/filesystems.php

• Modify the variable in disks/public/url:env :

    'disks' => [

        'local' => [
            'driver' => 'local',
            'root' => storage_path('app'),
        ],

        'public' => [
            'driver' => 'local',
            'root' => storage_path('app/public'),
            'url' => env('WEB_URL').'/storage',
            ...
