function Get-JIMConnectedSystemObjectChangeHistory {
    <#
    .SYNOPSIS
        Gets the change history for a Connected System Object in JIM.
 
    .DESCRIPTION
        Retrieves a paginated list of change records for the specified Connected System Object,
        ordered by change time descending (most recent first). Each record carries the initiator
        and run profile context, plus the per-attribute value changes.
 
        By default, returns a single page of results. Use -All to automatically paginate
        through all change records and return every row.
 
    .PARAMETER ConnectedSystemId
        The unique identifier (integer) of the Connected System the object belongs to.
 
    .PARAMETER Id
        The unique identifier (GUID) of the Connected System Object whose change history is being retrieved.
 
    .PARAMETER All
        Automatically paginate through all results and return every change record.
        Cannot be used with -Page.
 
    .PARAMETER Page
        Page number for paginated results. Defaults to 1. Cannot be used with -All.
 
    .PARAMETER PageSize
        Number of items per page. Defaults to 50. Maximum is 100.
 
    .OUTPUTS
        PSCustomObject representing change-history record(s).
 
    .EXAMPLE
        Get-JIMConnectedSystemObjectChangeHistory -ConnectedSystemId 1 -Id "12345678-1234-1234-1234-123456789abc"
 
        Gets the first page (50 most recent changes) for the specified CSO.
 
    .EXAMPLE
        Get-JIMConnectedSystemObjectChangeHistory -ConnectedSystemId 1 -Id "12345678-1234-1234-1234-123456789abc" -All
 
        Gets every change record for the specified CSO, paginating automatically.
 
    .EXAMPLE
        Get-JIMConnectedSystemObjectChangeHistory -ConnectedSystemId 1 -Id "12345678-1234-1234-1234-123456789abc" -PageSize 100
 
        Gets the first 100 changes (the maximum page size) for the specified CSO.
