feat(api:problemNum:submission): add endpoint `/api/submissions/[prob…

…lemNum]` ## what - add endpoint `/api/submissions/[problemNum]` - get submissions of a problem using problem number - if invalid `problem number` is given, a response of 400 will be returned - if the problem doesn't exist, a response of 404 will be returned - fetch problem submissions - add extra properties - verdict - fgColor - bgColor - title - fgHex - bgHex - language: convert language ID into a string - pnum: problem number - pTitle: name of the problem ## how ## why ## where - ./src/app/api/submissions/[problemNum]/route.ts ## usage
