Hard-Code high enough gas limit to make wallet happy

Currently, when the wallet asks the tx-executor to calculate a gas limit, it returns a response that will disconnect the transaction executor

As a demo
curl -XPOST -H "Content-Type: application/json" -d'{"method":"eth_estimateGas","params":[{"value":"0xde0b6b3a7640000","data":"0x2eca7b9b0000000000000000000000000000000000000000000000000000000000000001000000000000000000000000000000000000000000000000000000000000000100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001","to":"0x000000000000000000000000000000000000002a","from":"0x296000987df91481aa5652e421ae6f77c3f0bc7e"}],"id":"1b9eaaa58095aed12ecc4a88f3f53939","jsonrpc":"2.0"}' https://gamma-tx-executor-us-east.eximchain-dev.com

will return

{"jsonrpc":"2.0","error":{"code":-32000,"message":"gas required exceeds allowance or always failing transaction"},"id":null}

And this is the same request the wallet sends out. So, the tx-executor will need to be modified to properly send out a valid response rather than an error response. More research will be required to figure out why the node is complaining about being unable to just send the required gas amount.
