Pull request overview

This PR reduces circular-dependency risk in the Angular portal by extracting route-related enums out of app.routes.ts into dedicated enum files, and updating selected consumers to import those enums directly.

Changes:

• Moved AppRoutes into interfaces/portal/src/app/enums/app-routes.enum.ts.
• Moved ProgramMonitoringPaths into interfaces/portal/src/app/enums/program-monitoring-paths.enum.ts.
• Updated auth/MSAL-related code to import AppRoutes from the new enum location (and re-exported enums from app.routes.ts for backwards compatibility).
