Add Hamburger Menu for AdminPanel Sidebar on Mobile Devices.

Is your feature request related to a problem? Please describe.

We can't keep the AdminPanel sidebar open on mobile devices due to lack of space. So currently there's no way to access the AdminPanel sidebar on mobile devices.

Describe the solution you'd like

Add a hamburger menu icon (keep the color "yellow", the same as the theme color) to the navbar that will be visible on mobile devices & admin route only. When the hamburger icon is clicked, it should open the AdminPanel sidebar in a side drawer.

Also, make the "BUSIFY" text of the sidebar responsive for tablet screens(currently seems too small).
