I don't think you can mutate storages in offchain worker? at least the storages won't be saved. you need to use offchain worker db for that

TradingPairNodes type is CurrencyId->[CurrencyId], I think this datastructure is too complicate for offchain db. Current I'm moving this storage mutate part to on_idle.

remove TradingPairNodes, and direct calculate without on chain storage.

set_rebalance_swap_infoset the threshold and supply amount of token. if target swapped amount is less than threshold, no rebalance happened. We're using treasury account to do rebalance swap, so the treasury account should have balance for specified token.CurrencyId-> values:[CurrencyId]fromDEX::TradingPairStatuseswhich help decide the rebalance swap path in the case of pure DEX. i.e. if trading pair has [A,B],[A,C],[B,C], then datastructure is: A-[B,C], B-[C], and (A,B,C) can be rebalance path, the final trading path is Dex(A,B,C) + Dex(C,A).RebalanceSwapPaths, it's only used by offchain worker, not used by normal aggregated dex swap.or 3USD pool: Taiga(AUSD,USDC)+Taiga(USDC,USDT)+Taiga(USDT,AUSD).
