[ENHANCEMENT] Add an admin account

[SethCram]

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

• Yes, there should be some features available for maintenance and additional not available to regular users

Describe the solution you'd like

• Add an admin account that can create new categories, and do other things

Describe alternatives you've considered

• these things could be added as needed manually thru mongoDB Atlas interface

Additional context

• could be implemented through manual change to user model using a "isAdmin" boolean field
  • then use this field to differentiate between logged in users + logged in admin users

Development

• manual change to user model using an "isAdmin" boolean field

  • not done during [ENHANCEMENT] Use Jason Web Token (JWT) for verification #19
  • implemented now

• manually make an account an admin

  • password should be very strong
  • done during [ENHANCEMENT] Use Jason Web Token (JWT) for verification #19
  • impls server side auth thru JWT since isAdmin field held within JWT and it's decoded by verify method

• let them delete or update any post

  • isAdmin not properly set within jwt
    • possibly bc isAdmin init'd to a boolean?
    • change to user model had not been impl'd yet

• let them update any comment

  • comment deletion not yet implemented

• let them delete any user

  • linked btn on sidebar
  • ensured jwt auth'd to check isAdmin

• let them delete comments

  • proposed in [ENHANCEMENT] Comment section improvements #34 for author too
  • root comment deletion works properly
  • when try to delete a reply comment, deletes it but doesnt rm it from root comment's replies arr
    • would be easier if every reply comment had a "rootComment" field
    • wouldn't have to follow the chain of replyId's
    • did alota this rework in [BUG] Comment related bugs #38
  • used the pull operation to rm the subdocument from the root comment
  • verified it worked on all manner of comment types by author and admin

• let them delete categories

  • would also needa delete the category from the posts it's linked under if any?

• create + let them access admin dashboard

  • but should only be accessible by admins
  • all admin privileges and responsibilities should be consolidated here
    • such as all posts or comments that've been flagged
    • and fake data insertion/deletion

• allow admin to remove all flags from a post/comment

  • requires [ENHANCEMENT] Allow for post + comment flagging #47

• could allow them access to running fake data insertion and deletion script via a form

  • not sure how to link cmd line script to frontend tho
