Failed to do initial token approval using openocean_binance-smart-chain_mainnet

Steps:
Approve tokens on the exchange/bot side
Create/start amm_arb strategy using openocean_binance-smart-chain_mainnet

Actual:
Failed to start strategy, bot stuck into openocean_binance-smart-chain_mainnet not ready: waiting for allowances: use trading interface to do manual approval..

Expected:
Bot use token that approved manually on metamask and calculate profitability

Same wallet using sushiswap_binance-smart-chain_mainnet

Same thing for openocean_ethereum_arbitrum_one and openocean optimism, not ready: waiting for allowances: use trading interface to do manual approval..

However works for uniswap_ethereum_arbitrum_one

PR update:

• Run endpoint tests using thunder client
• Port, wallet {add, remove}, balances and poll all ok ✅

However for arbitrum and optimism we are not able to proceed with allowance and approve endpoints and getting the same behavior reported above. While the previous commend shows issue on binance-smart-chain, we are able to run the endpoints without any issues at the moment

Arbitrum one

Optimism

LGTM,
Ethereum optimism and arbitrum, BSC and Cronos added for openocean
Checked balance successfully for openocean on the added connector chains

Note: there's ongoing issue with allowances/approval mentioned above
