Introduce txpool.PendingFilter and migrate Pending(...) signatures from positional params to a typed struct. - Add core/txpool.PendingFilter with MinTip/BaseFee fields for cheap call-site filtering - Update txpool subpool interface and all call sites in eth/miner to pass the filter struct - Keep behavior unchanged for empty filter (equivalent to previous nil,nil usage) - Refresh legacypool tests to use the new API shape This is a refactor-only change intended to improve API clarity and future extensibility without changing consensus or RPC semantics.
