Update renFIL rate strategy on Aave v2 Ethereum

The proposal uses the standard Aave governance payload pattern: a single action calling execute() on a dedicated payload contract, which internally performs the actual logic (in this case, calling setReserveInterestRateStrategyAddress on the PoolConfigurator). This decoded action alone does not reveal the internal call, since it is not statically decodable without tracing execution or reviewing the payload contract's source code. However, the description provides links to the verified source code of both the payload contract and the new rate strategy contract, and the specification section explicitly describes the single expected internal action, which matches the well-established pattern for this type of proposal. There is nothing in the visible calldata that contradicts the description, and no additional actions, transfers, or role changes are present beyond the single execute() call. Given the inherent limitation of not being able to decode the internal delegatecall behavior from the top-level trace alone, confidence is medium rather than high, but there is no evidence of a mismatch between the stated intent and the on-chain action structure.
