Fixes #7

Summary

42 tests covering all public methods of UsageBillingService
Usage recording: event creation, aggregation, idempotency, feature flag gating, inactive meter handling
Workspace-level recording: active subscription lookup, missing subscription guard
Usage retrieval: current period, meter filtering, summaries with charge estimates, history with pagination
Billing and invoicing: pending charge calculation, invoice line item creation, billed-state marking, zero-charge skipping
Overage and tiered pricing: flat-rate charges, multi-tier graduated pricing, tier boundary transitions
Billing cycle resets: fresh records for new period, inactive meter exclusion, previous period preservation
Usage aggregation: event-to-record rollup, zero-quantity defaults, idempotent re-aggregation
Meter CRUD: create, update, active listing with ordering
Stripe integration: early-return guards for non-Stripe gateways

Test plan

All tests follow existing Pest conventions used across the test suite
Lint passes (composer run lint)
Full test suite requires Core\Tenant dependency (same as all existing feature tests)
