Two lint fixes, both test-only (no effect on the infra artifact version):
- annotate the TestAdoptable / TestKillInfraFirecrackers helper params
(reportMissingParameterType).
- test_docker_test_helpers: read __unittest_skip__ via getattr on the
dynamically-built Case type, matching the sibling assertion — pyright can't
see the attribute the skip decorator adds (reportAttributeAccessIssue).
