fix: remove tabulate dependency and skip blockchain RPC test in CI

- Remove tabulate dependency from cross_chain commands
- Use simple string formatting for rate table output
- Add cross-chain to CLICK_COMMANDS list
- Skip blockchain RPC test when no node available in CI
- Update scenario documentation
