Prop 13: Add Keplr validator

Keplr is the largest wallet in the Cosmos ecosystem, trusted by over 2 million users. It also supports EVM and non-EVM chains, including Bitcoin and Starknet. In addition to the core Keplr Wallet, we offer a comprehensive suite of companion products, including Keplr Mobile, the Dashboard, the Multisig Dashboard, and the Validator Dashboard. Beyond our user-facing products, Keplr Infra has been actively operating as a validator on over 20 networks, consistently ranking among the top-tier validators. We also provide high-SLA RPC infrastructure for over 50 Cosmos-based chains and more than 7 EVM chains, dedicated to Keplr users. Our infrastructure spans over 150 servers across 6+ cloud and bare-metal providers — including our own on-premise servers — and has been operated reliably for over three years. It is enterprise-grade, ensuring high availability through finely tailored optimizations and 24/7 monitoring.
