v1.1.10 - Prefer fresh FP telemetry for Hub A1

This patch uses the new v1.1.9 runtime evidence: fresh app-side system telemetry is arriving from the FP row on each refresh, while EL100V2 is behaving like pack/detail telemetry and HA1-specific endpoints still return online-only data. Hub A1 related fallback now prefers fresh FP/Apex system telemetry and only allows battery SOC/SOH/voltage through that system-source path, keeping the stale EL100V2 guard intact.
