- New app/models/essential.py with Essential model and EssentialType enum (feature, improvement, refactor) - Fields: id, essential_code (unique), proposal_id (FK to proposes), type, title, description, created_by_id (FK to users), created_at, updated_at - Added essentials relationship to Proposal model (cascade delete-orphan) - Added essentials table auto-migration in main.py _migrate_schema() - Registered essential module import in startup()

the Essential → story-task mapping (see BE-PR-008).
