Chore: Remove dev dependencies for production deployment

- Removed devDependencies section (nodemon) from package.json
- Removed "dev" script that referenced nodemon
- Reinstalled with --omit=dev flag
- Reduced node_modules from 8.4MB (105 packages) to 6.6MB (78 packages)

Only production dependencies remain:
- express (web server)
- mysql2 (database driver)

This creates a cleaner, smaller package for production deployment.
