Feature: #108831 - Extend workspace preview links to all records 

Description 

The Workspaces module previously generated shareable preview links (with ADMCMD_prev token) for pages only. This change extends the functionality to support any record type.

The preview page for non-page records is determined via existing user TSconfig options:

• options.workspaces.previewPageId.<table>
• TCEMAIN.preview.<table>.previewPageId

Additional query parameters can be configured via:

• TCEMAIN.preview.<table>.fieldToParameterMap
• TCEMAIN.preview.<table>.additionalGetParameters

Example configuration for a custom record type:

TCEMAIN.preview.tx_myext_domain_model_item {
    previewPageId = 42
    fieldToParameterMap {
        uid = tx_myext_pi1[item]
    }
    additionalGetParameters {
        type = 9818
    }
}

Impact 

The QR code and shareable link button in the Workspaces module now work for all record types that have a preview configuration. This allows editors to share workspace previews of custom records with colleagues or clients without requiring them to have a backend login.
