fix(wallet)_: fix crash on cbridge fee calculation

[IvanBelyakoff]

Closes #19610

cbridge does not handle such small values, though we pass them correctly:
"{\n \"err\": {\n \"code\": 500,\n \"msg\": \"amount should \\u003e 0\"\n },\n \"eq_value_token_amt\": \"\",\n \"bridge_rate\": 0,\n \"perc_fee\": \"\",\n \"base_fee\": \"\",\n \"slippage_tolerance\": 0,\n \"max_slippage\": 0,\n \"estimated_receive_amt\": \"\",\n \"drop_gas_amt\": \"\",\n \"op_fee_rebate\": 0,\n \"op_fee_rebate_portion\": 0,\n \"op_fee_rebate_end_time\": \"0\"\n}" url="https://cbridge-prod2.celer.app/v2/estimateAmt?src_chain_id=1&dst_chain_id=10&token_symbol=WETH&amt=10000&usr_addr=0xaa47c83316edc05cf9ff7136296b026c5de7eccd&slippage_tolerance=500" amountIn=10000
It returns err, that amount should be > 0 and base_fee and perc_fee are empty, so we can't parse them into a bigInt anf get nil.

@IvanBelyakoff - can we include an informative description here?
I understand the issue includes the error, but perhaps you could explain the solution at a high level etc 👍
