fix: update workflows for Go 1.25.1 and SSH deployment

Test workflow:
- Upgrade golangci-lint-action from v6 to v7
- v7 is required for golangci-lint v2.x support
- Remove skip-cache as v7 handles caching better

Deploy workflow:
- Fix SSH heredoc to use unquoted ENDSSH delimiter
- Allows environment variables to expand in remote session
- Fixes "Permission denied" by properly passing REPO_PATH and SERVICE_NAME
