context: |
  T027.S4 completed TLS for critical path services (IAM, Chainfire, FlareDB).
  This task covers the remaining 5 services plus operational improvements:
  - PlasmaVMC: VM management API (external-facing)
  - NovaNET: Network control plane (internal + tenant-facing)
  - FlashDNS: DNS service (external-facing, security-critical)
  - FiberLB: Load balancer control (internal)
  - LightningSTOR: Storage service (internal)

  TLS configuration pattern established in T027:
  - specifications/configuration.md documents TLS config schema
  - scripts/generate-dev-certs.sh creates dev certificates
  - File-based secrets at /etc/centra-cloud/certs/

acceptance:
  - All 5 services compile with TLS support
  - TLS configuration wired via unified config approach (clap + config file)
  - Certificate generation script updated for new services
  - NixOS module updates for new certificate paths
  - Integration test verifies TLS connections work

  **COMPLETE 2025-12-10**: All 8 services now have TLS support.
  - Phase 1 (T027): IAM, Chainfire, FlareDB
  - Phase 2 (T031): PlasmaVMC, NovaNET, FlashDNS, FiberLB, LightningSTOR

  **Pattern from T027 Phase 1:**
  ```rust
  // TLS config pattern (from IAM)
  #[derive(Debug, Clone, Deserialize)]
  pub struct TlsConfig {
      pub cert_path: PathBuf,
      pub key_path: PathBuf,
      pub ca_path: Option<PathBuf>,  // For mTLS
  }
  ```

  **Priority rationale:**
  - P0: External-facing services (PlasmaVMC, NovaNET, FlashDNS)
  - P1: Internal services (FiberLB, LightningSTOR)
  - P2: Infrastructure (NixOS modules, cert rotation)

  **Future work (out of scope):**
  - Automated certificate rotation (Let's Encrypt integration)
  - External PKI integration
  - mTLS for all internal communication
