Contest & Problem section + User Schema revamp

[mihaicodes]

TODO

Language guide:

• (?) = Not sure, maybe do this.

Problem adding interface

• Problems should have tags, including programming language tags and written language tags

• They can be written either in Romanian, English or both, in which case the user can choose through a top-left button the preferred language

• The problem interface already is similar to Leetcode so this should be easy to implement
  User ranks:

• Member

  • (In itself in the future it will have subranks based on solved problems, different from any other ranking system so far, we'll have a chat later about this, it's what I wanted to implement in my own platform).
  • View, Search and solve problems and participate in contests.

• Problem Writer

  • This rank should be able to add problems through a UI. The problems are then staged and verified by us or an LLM model that removes obscenities and rewrites the problem with the same context or a nicer one. Easy to do.
  • (?) Possibly organize contests like on Codeforces

• Moderator

  • BitByBit Contest help desk if needed, removes obscenities manually, (?) disqualifies users if cheating is involved.
  • No access high enough to destroy the platform, but high enough to decide whether users need to be on a timeout due to obscenities.

• HelixDev

  • Our ranks, nothing more than a decorative badge and maybe some custom-looking user profiles, we have the same permissions as all ranks below us.
  • Highest rank there is, obtained only through contributing quality code to the project.
