- Removes `AssetsPricesHelper` class by inlining `fetchPrices` at its two call sites (`BraveWalletPanel` and `Utils`) with direct `assetRatioService.getPrice()` calls, eliminating an unnecessary `MultiResponseHandler` wrapper.
- Moves price lookup helpers (`getPrice`, `getPriceForAsset`, `parseAssetPrice`) into Utils.java where all callers already have access.
- Removes the now-unused `FetchPricesResponseContext` from `AsyncUtils`.
- Fixes copy-paste bug in `ParsedTransaction` where `minBuyAmountArg` was reading `txArgs[1]` (same as `sellAmountArg`) instead of `txArgs[2]`, confirmed against the desktop C++ implementation in `eth_data_parser.cc`.
- Fixes general warnings for `ParsedTransaction` class.
- Improves Javadocs.
