Farm Management SaaS

This phase adds the responsive app shell, placeholder home dashboard, and the full settings/definitions module across Flutter and Node.js.

Settings API

• Base path: /api/v1/settings
• Auth: existing in-house JWT middleware in backend/src/core/middleware/auth.middleware.js
• Firestore storage: users/{uid}/settings/{entity}/items/{docId}

The original prompt used users/{uid}/settings/{entity}/{docId}. Firestore alternates collection and document segments, so this implementation stores entity metadata at users/{uid}/settings/{entity} and the actual records in that entity's items subcollection.

Recommended Firestore indexes

• Single-field descending index on createdAt for each settings items subcollection
• Composite index on groupId + subGroupId for products
• Composite index on townId + sectorId for customers
• Composite index on townId for sectors

See firestore.indexes.json for a starting point.
