openmf/web-app ? reverse-engineered prompt

Build me a modern web app for the Mifos X platform that lets people sign in and manage financial services from a clean dashboard. It should feel like a real production banking style app, with a polished Angular Material interface, responsive layouts, and support for common admin and customer workflows like viewing clients, loans, accounts, and reports.

Please wire it up so it can talk to an Apache Fineract backend through a proxy during development, and make it easy to switch between local and demo API settings. Include sensible environment based configuration, basic login support, and the usual build and run setup so I can start it locally or run it in Docker.

If anything needs current Angular or backend setup details, look them up online and use the latest stable approach.
