+ * Lifecycle:
+ *  - `start()` — loads from the DB; if empty, seeds from legacy constructor
+ *    fields (`tls.contactEmail`, `smartProxyConfig.acme.*`) on first boot.
+ *  - `getConfig()` — returns the in-memory cached `IAcmeConfig` (or null)
+ *  - `updateConfig(args, updatedBy)` — upserts and refreshes the cache
+ *
+ * Reload semantics: updates take effect on the next dcrouter restart because
+ * `SmartAcme` is instantiated once in `setupSmartProxy()`. `renewThresholdDays`
+ * applies immediately to the next renewal check. See
+ * `ts_web/elements/domains/ops-view-certificates.ts` for the UI warning.
