test(backend): add tests for SERVER_BINARY, SERVER_PARAMS, STEAMCMD_PATH env vars

- TestStartWithServerBinaryEnv: custom binary name via env - TestStartWithServerParamsEnv: overridden params via env - TestServerParamsEnvOverridesSettings: env takes precedence over settings - TestSteamCmdManager_SteampathEnv: custom steamcmd path via env
