generalize StablePay to support multiple Djed/Gluon stablecoins and ERC20 base assets #84
Description
- System : Generalized the architecture to support multiple stablecoin deployments per network via an array-based configuration structure.
Protocol : Integrated Djed Isis/Tefnut protocols and new Oracle types (Chainlink, API3, HebeSwap) into the core SDK logic.
ERC20 Base Assets: Implemented a mandatory "Approve" transaction flow for non-native assets to handle ERC20-backed stablecoin purchases.
UI/Core Alignment: Updated TokenDropdown and Transaction classes to dynamically resolve and initialize specific protocol logic from the new configuration.
