refactor(config): restructure Args init flow and WitnessInitializer

- Restructure Args.setParam into 4-step flow: parse CLI, apply config,
  apply CLI overrides, init witnesses
- Rename setParam(Config) to applyConfigParams, setCLIParameter to
  applyCLIParams for clarity
- Extract WitnessInitializer into 3 static methods (initFromCLIPrivateKey,
  initFromCFGPrivateKey, initFromKeystore) with routing in Args
- Remove password/privateKey/witnessAddress/help/version/configFilePath
  from CommonParameter — pass as method params instead of global state
- Move JDK version check from Args to FullNode entry point
- Extract Configuration.getByFileName for single-param config loading
