Cicd code coverage addition megan azmanov

[Megan235]

Summary

• Sets up code coverage enforcement across all three services, replaces Hibernate's auto schema management with Flyway migrations, locks in the engine, backend communication model (engine never touches the DB directly), adds pgAdmin for local database access, and scaffolds the full feature-based folder structure for the six core use cases (Login, Signup, PreferenceProfile, Pantry, Dashboard, Recipe Vault).

What's included

• Database- Flyway now owns the schema, migration files live in database/ at the repo root, Hibernate set to validate only
• Code coverage- JaCoCo (backend), pytest-cov (engine), Flutter coverage with lcov filtering, all enforced at 80% with per-service flags on Codecov
• Engine architecture- talks to the backend via HTTP
• pgAdmin- optional tools profile in Docker Compose, accessible at localhost:5050
• File structure -feature-based packages (auth, pantry, preference, vault) on the backend, matching core/features/shared/ layout on the frontend

to note

• pom.xml has exclusions for code coverage, this will have to be removed as backend features developed (this is to allow scaffolding empty files to pass)
• Engine is excluded from code coverage and will be added in a later sprint
• Flutter has placeholder tests for ci to pass to allow for scaffolding files.
