All 7 handler files now have test coverage: jobs (14 tests), notifications
(11), policies (15), issuers (15), targets (14). Negative-path integration
tests cover nonexistent resources, invalid payloads, malformed CSR, expired
cert lifecycle, and method-not-allowed errors. CI now enforces coverage
thresholds (service 60%+, handler 50%+) and includes connector tests.
