Add mapping for PObjectStateHist and new DTO record

Introduced a mapping configuration in `MappingProfile` to map `PObjectStateHist` to `ObjectStateHistDto`, including the `Intl` property and an array of `Others`. Added a new record `ObjectStateHistDto` with properties for `Intl`, `Others`, `ChangedWho`, and `ChangedWhen`, initializing `Others` to an empty array of strings.
