feat/Add Admin Dashboard with complete control

[bhutoria]

Add Admin Dashboard with ability to add tracks, edit tracks, create MCQ questions, create code questions

• Tracks should be added directly from the dashboard with ability to revalidate ssg cache for each track.
• MCQ questions can be added for each track directly through the dashboard
• Code problems (as #112 )

Would like to work on this - since people are working on DSA problems and mcq already - could only work on creating tracks and revalidating cache.

hey I can do it. Does it have to be approved by someone? (I am new here)..

[bhutoria]

@hkirat, would like to work on this, can this be assigned to me?

[ShubhamMewara]

it is done #152

[bhutoria]

Looks good.

Doesn't seem to be protected by authentication though and we need to link every track to a set of problems - i.e, tracks and problems have a one to many relationship.

@bhutoria #129 is not merged we don't have auth right now. will work on that
