Add solana support to contract transmitter

[huangzhen1997]

Jira ticket

This PR removes EVM dependent code (specifically the address encoding logic) in plugin oracle creator + contract transmitter. There will be two separate PR for refactoring CR+CW logic.

I'd prefer to error or panic here if encounter an unknown family. That will make it explicit to developers to support a new family here too, instead of silently returning null string.

Why: The triggered workflow did not complete successfully. The conclusion status was "failure" instead of "success," which caused the upstream job to propagate the failure.

Suggested fix: Investigate the logs of the triggered workflow at https://github.com/smartcontractkit/operator-ui/actions/runs/12757731294 to identify the specific reason for the failure and address the underlying issue.
