feat(mtls): implement mTLS/CA + bootstrap token framework [tsk_FUQws_DMIcXa]
ECDSA P-256 self-signed CA with disk persistence (load-or-generate),
CSR signing (CN=nodeUUID, 90d validity, EKU=ClientAuth), one-time
bootstrap tokens via Redis GETDEL (15min TTL), CRL revocation with
Redis SET + DB interface, gRPC unary+stream interceptors that extract
CN from verified TLS chains (Enroll whitelisted, others require cert),
and NewServerTLSConfig (VerifyClientCertIfGiven + TLS 1.3 + CRL hook).
Frozen API: SignCSR / CAPEM / IssueToken / ConsumeToken / Revoke /
NewServerTLSConfig / UnaryServerInterceptor / NodeUUIDFromContext
Tests cover: CA sign+verify, token one-time guarantee, TTL expiry,
revocation rejection, interceptor whitelist (5 categories).
Redis layer backed by miniredis in tests.
Run setup.sh from server/ to fetch deps and verify tests pass.
