- C1/H4: rating cron only rates subs on the charge's own plan_id
- C1: _fc_rate_usage skips creating a line when amount is 0 (still updates existing)
- C2/C4: /usage authorizes each event (exists + is_subscription + linked customer)
- C3: API handlers validate input and return 4xx-shaped errors instead of raising;
controller maps status=='error' to HTTP 400
- H1: cron uses real billing window [last_invoice_date or start_date, next_invoice_date)
- H2: _aggregate uses half-open window anchored on period_start
- H3: idempotency scoped to (subscription_id, metric_id, idempotency_key)
- H5: webhook stores canonical body, signs+POSTs it verbatim, adds X-Fusion-Event-Id,
caps backoff at 2**min(attempts,10)
- H6: SSRF guard rejects non-https / localhost / private / link-local webhook_url
- M7: charge_model reduced to standard/package (dropped unimplemented graduated/volume)
- L1: currency_id required on charge + reconciliation
- L2: charge price non-negative + unit_batch positive DB constraints
Adds 17 regression tests (suite 22 -> 39, all green via fcb_test_on_trial.sh).
