Pull request overview

This PR appears to consolidate MongoDB connection configuration to a single MONGODB_URI environment variable and applies minor formatting/cleanup changes across the server routes/middleware and the client lockfile.

Changes:

• Switch model connection strings in staff/paper (and intended in article) to use process.env.MONGODB_URI.
• Apply small style/formatting fixes in Express routers/middleware (whitespace, chaining layout, semicolon).
• Update client/package-lock.json by removing some optional @emnapi/* entries.
