Prop 33: Software Upgrade: Arkeo Core v1.0.16.1 (Dynamic Services + Provider Enhancements)

Upgrade to v1.0.16.1 introduces the dynamic on-chain service registry (no store migrations), improves provider handling, and fixes provider claim payment validation and signature handling. Validators must upgrade to the v1.0.16.1 binary before the scheduled height; Cosmovisor is recommended to minimize downtime.
