fix(billing): Plan 4 Task 2 code-review fixes (2 Important + 1 Minor)
- PricingTierResolver::resolveForCount — InvalidArgumentException на
$leadOrdinal < 1 (closes I-1: defensive contract validation).
- PricingTierRepository::activeAt — explicit @var Collection<int,
PricingTier> annotation для type narrowing (closes I-2; firstOrFail
отвергнут — Stan ругается на Eloquent\Model return-type).
- PricingTierResolverTest — +1 unit test (8/8 PASS): throws на 0/-1.
- PricingTierRepositoryTest — +1 integration test (5/5 PASS): excludes
inactive tiers (closes M-2 coverage gap).
