Pull request overview

This PR refactors backend configuration and database wiring (moving from app.core.config / app.db.* to app.config.* / app.database.*), and tightens user role handling so clients can’t self-assign roles during registration or profile updates.

Changes:

• Enforce server-side default user role (analyst) during registration and prohibit role updates via profile edits.
• Introduce new app/config and app/database modules (Postgres engine/session + shared SQLAlchemy Base) and update imports accordingly.
• Add .env ignoring and a simple authentication-flow diagram file.
