feat(stellar): add deployment script for testing

[hydrobeam]

closes AXE-5754

Summary

• The script was adapted from test-sui.yaml. It executes the things that can be done via the stellar/*.js files.
  • currently missing testing for approve under gateway.js
  • and missing testing for execute under operators.js
  • refund won't work due to a missing gas service contract
  • also --estimate-cost for the operators contract currently doesn't work:

cpu_instructions: Number(response.cost.cpuInsns),                                               
TypeError: Cannot read properties of undefined (reading 'cpuInsns')

• To enable connecting to http networks, allowHttp needed to be specified in various locations throughout the js files.
• Also corrected an instance of pulling the wrong network password (STANDALONE is correct, not SANDBOX)
• manually fetching the stellar-cli binary because the compilation process was very long. tried using cargo binstall to avoid the wget + curl business, but there appears to be some upstream issue:

cargo binstall stellar-cli

Do you wish to continue? [yes]/no

note: the wallet step can't be setup immediately after spinning up the network, otherwise you encounter timing errors
