[TASK] Implement WorkspacesAwareRecordService in AbstractPageController
[TASK] Introduce constant for raw template dok type
[BUGFIX] Infinite loop when reading page rootline in workspace mode
[BUGFIX] Use original record as emulated parent for versioned records

This makes inheritance resolving in PageService include the original record as an emulated first parent record in the root line of a record, if said record is a versioned record. The effect propagates all the way through the root line, resolving the original record's parent values for each record in the root line.
