Add a `bun run setup` command to seed data

[AbhayVAshokan]

• Throw an error if the bun run setup command if DATABASE_URL contains the word prisma. This would prevent accidental modification of the production database.
• Delete and re-create the database leetify.
• Seed say top 10 valid Leetcode users. This will ensure "Sync problems" button is functional.
• Seed at least 10 problems for each user.
• Randomly mark several problems as favorite.
• Seed any other valid information.
