Tyler cf9af8e1d9 docs: add DB + reconciliation design spec (sub-project 2 of 4)
Replaces the in-memory store with SQLite via SQLAlchemy 2.0; adds
automatic 837P ↔ 835 reconciliation on every 835 parse; ships a
manual /reconciliation page; extends the claim lifecycle to a
7-state model with reversal handling.

Key decisions (locked from brainstorming):
- SQLite at ~/.local/share/cyclone/cyclone.db, overridable via
  CYCLONE_DB_URL (Postgres escape hatch)
- SQLAlchemy 2.0 sync ORM; PRAGMA user_version migration runner
- Strict auto-match on patient_control_number (CLM01 == CLP01)
  within +/-7 days of service_date
- 7-state claim model with reversal that sets Claim.state=REVERSED
  and preserves prior state on Match.prior_claim_state
- Reconciliation triggered inside store.add() after ERA persist;
  fail-soft (logged + activity event, never blocks parse)
- 3 new API endpoints; new /reconciliation page; same palette
  and aesthetic voice as sub-project 1

Spec is approved-section-by-section and self-reviewed.
