feat: align OpenRPC server with simplified client API

- Updated RegisterRunnerParams to only require name (queue = name)
- Added AddRunnerParams with RunnerConfig for add_runner method
- Updated RunnerManagementParams and StopRunnerParams with secrets
- Added add_runner method to OpenRPC trait and implementation
- Removed duplicate AddRunnerParams definition
- Updated client register_runner to send params as JSON object
- Added TODO comments for moving secrets to HTTP headers
