Async Update The Manager

to make the manager as much reliable as possible, we need a way to update the manager files list when any operation is made "upload, delete, rename, etc..".

so up until now every user was on his own, until the cache is cleared or he tries to do something on an item that isnt really there & get hit with an error.

so to fix all of that we now use websockets through laravel-echo, which is optional but if you want to get the best experience possible, then make sure to follow the docs and install it.

Notes

• the manager broadcast using ->toOthers() to make sure the user don't get a double modification when he do any operation,
  so in-order for that to work make sure that you register echo after axios, otherwise the laravel defaults wont work.
