Allow specifying PositionSize wolverine order properties (#9257)

* feat: add MappedSynchronizingHistoryProvider base class

Introduces an abstract class for history providers that handle symbol mapping and time-aligned data slices. Uses IMapFileProvider to resolve ticker changes, provides an abstract method for mapped history retrieval, and overrides GetHistory to synchronize results. Enables nullable reference types and adds documentation.

* Minor tweaks
