feat(P08): CA, CSR, fingerprint, rotation, redact, TLS config + cert repo
Internal CA with CSR join, mTLS 1.3 config builders, rotation alarm,
PEM redaction, and cert inventory schema (REQ-033/034/035/036).
- internal/security/ca.go: CAInit/LoadCA/SignCSR, file mode enforcement
(ca.crt 0644, ca.key 0600) per REQ-033
- internal/security/csr.go: GenerateCSR with DNS + IP SANs (REQ-036)
- internal/security/fingerprint.go: SHA-256 hex of cert DER
- internal/security/rotation.go: 30d pre-expiry alarm, history pruning
- internal/security/redact.go: PEM private key block stripping (REQ-035)
- internal/security/tls_config.go: TLS 1.3 with AEAD allowlist
- internal/security/certgen_test.go: round-trip + mode + rotation + redact
- internal/store/migrations/0004_certs.sql: cert inventory table
- internal/store/cert_repo.go: CRUD + PruneOlderThan (REQ-025)
