  (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()

"""Essential model — actionable items under a Proposal.
Each Essential represents one deliverable scope item (feature, improvement,
or refactor). When a Proposal is accepted, every Essential is converted into
a corresponding ``story/*`` task under the chosen Milestone.
See: NEXT_WAVE_DEV_DIRECTION.md §8.5
