feat(M45): ACME certificate profile selection, ARI RFC 9773 renumber, 45-day renewal positioning

Three related ACME ecosystem changes shipped as a single milestone:

1. ACME Certificate Profile Selection: Custom JWS-signed newOrder POST with
   `profile` field (e.g., `tlsserver`, `shortlived` for 6-day certs) bypassing
   acme.Client.AuthorizeOrder() since golang.org/x/crypto lacks profile support.
   ES256 JWS signing with kid mode, nonce management, directory discovery.
   Empty profile delegates to standard library path (zero behavior change).
   Configurable via CERTCTL_ACME_PROFILE env var. GUI: profile dropdown on
   ACME issuer config.

2. ARI RFC 9702 → 9773 Renumber: All 25+ references updated across Go source,
   docs, README, and examples. Zero remaining occurrences of RFC 9702.

3. 45-Day / Short-Lived Certificate Positioning: 5 domain tests validating
   renewal thresholds against SC-081v3 validity reduction timeline (200→100→47
   days) and Let's Encrypt 45-day/6-day profiles. ARI (RFC 9773) is the
   expected renewal path for 6-day shortlived certs.

New tests: 13 profile + 5 domain threshold + 1 frontend = 19 new tests.

certctl works with any certificate authority, not just ACME providers. Seven issuer connectors ship today, all free:
- **ACME v2** (Let's Encrypt, ZeroSSL, Google Trust Services, Buypass) — HTTP-01, DNS-01, DNS-PERSIST-01 challenges, External Account Binding, ACME Renewal Information (RFC 9702)
- **ACME v2** (Let's Encrypt, ZeroSSL, Google Trust Services, Buypass) — HTTP-01, DNS-01, DNS-PERSIST-01 challenges, External Account Binding, ACME Renewal Information (RFC 9773)
- **HashiCorp Vault PKI** — `/v1/{mount}/sign/{role}` API, token auth
- **DigiCert CertCentral** — async order model, OV/EV support
- **step-ca** (Smallstep) — native /sign API with JWK provisioner auth

### vs. Enterprise Platforms
Venafi and Keyfactor offer decades of features at $75K-$250K+/year. certctl targets organizations that need 80% of those capabilities at a fraction of the cost. What certctl doesn't have yet: SSO/RBAC (coming in certctl Pro), vendor SLA-backed support. What certctl does have that enterprise platforms don't: an MCP server for AI-assisted management, ACME ARI (RFC 9702) for CA-directed renewal timing, and a deployment model that works in 5 minutes instead of 5 months.
