…actClient BREAKING CHANGE: The contract client now makes real Soroban RPC calls instead of returning hardcoded mock data. Previously, buildContractCall() returned a fake XDR string and simulateContractCall() returned hardcoded values (e.g. score was always 45). This made the entire type-safe client non-functional for real blockchain interactions. Changes: - Read operations now use real server.simulateTransaction() via Soroban RPC to query on-chain state - Write operations build real transaction XDR using TransactionBuilder + Contract.call(), signed via Passkey + Launchtube sponsorship - Added comprehensive input validation for addresses (G.../C...), scores (0-100 range), and tier values (TIER_1/2/3) - Added environment variable validation with clear error messages for missing NEXT_PUBLIC_RISK_TIER_CONTRACT_ID - Lazy initialization prevents SSR/build failures when env vars are absent - Source account resolution handles both traditional (G...) and smart contract (C...) addresses with automatic friendbot funding on testnet Closes mericcintosun#16 (Smart Contract Type Bindings) Closes mericcintosun#18 (Input Validation and Sanitization) Closes mericcintosun#15 (Environment Variables Validation)
