fix: replace console.log/console.error with proper logging in monitoring and themes routes

- monitoring.js: Added log dependency, replaced console.log with log.warn
- themes.js: Added log dependency, replaced console.error with log.error
- src/app.js: Pass log to monitoringRoutes and themesRoutes

This fixes error messages being lost to stdout instead of proper log files.
