Add comprehensive ACME test suite (60 tests, 2100 lines)
Test coverage for the entire ACME server implementation: - helpers_test.go: memBarrier, key generation, JWS/EAB signing, test fixtures - nonce_test.go: issue/consume lifecycle, reuse rejection, concurrency - jws_test.go: JWS parsing/verification (ES256, ES384, RS256), JWK parsing, RFC 7638 thumbprints, EAB HMAC verification, key authorization - eab_test.go: EAB credential CRUD, account/order listing - validate_test.go: HTTP-01 challenge validation with httptest servers, authorization/order state machine transitions - handlers_test.go: full ACME protocol flow via chi router — directory, nonce, account creation with EAB, order creation, authorization retrieval, challenge triggering, finalize (order-not-ready), cert retrieval/revocation, CSR identifier validation One production change: extract dnsResolver variable in validate.go for DNS-01 test injection (no behavior change). All 60 tests pass with -race. Full project vet and test clean. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
