refactor(remote-config): Disable in CEC mode + add observability logs

[tonidero]

2 main changes in this one:

• Disable Remote Config in CEC mode
• Add some logs to better know what remote config is doing

---

Note

Low Risk
Changes are gated CEC wiring plus logging and small read-path optimizations; no new network or entitlement logic for standard SDK builds.

Overview
Remote Config is no longer wired up when the SDK runs in custom entitlement computation (CEC) mode — RemoteConfigManager is only created when the feature flag is on and appConfig.customEntitlementComputation is false.

Observability is expanded across the remote config stack: refresh start, 204 handling, persist/prefetch, cold reads, topic/blob resolution, blob download failover, and prefetch enqueue counts. Most of this is verboseLog; successful config receipt/persist and unchanged 204 responses use debugLog, with warnLog when a blob download succeeds but read-back fails.

Minor behavior tweaks alongside logging: topic() only waits for or triggers a sync when the topic is not already cached; inline blob extraction logs success only when write() actually stores the blob.
