Add missing Google Places API properties to fix issue #157 (#175)

This commit adds 23 missing properties to the PlacesDetails Result entity
and creates 3 new supporting entity classes to match the official Google
Places API documentation.

New entity classes:
- BusinessStatus enum for operational status
- PlusCode class for location references
- PlaceEditorialSummary class for place summaries

New properties added to Result class:
- Business features: CurbsidePickup, Delivery, DineIn, Takeout
- Accessibility: WheelchairAccessibleEntrance
- Services: ServesBeer, ServesBreakfast, ServesBrunch, ServesDinner, ServesLunch, ServesVegetarianFood, ServesWine
- Enhanced metadata: BusinessStatus, EditorialSummary, PlusCode, IconBackgroundColor, IconMaskBaseUri
- Opening hours: CurrentOpeningHours, SecondaryOpeningHours
- Events: Event property
- Ratings: UserRatingsTotal

All new properties use nullable types to maintain backward compatibility
and prevent deserialization issues. Existing property names preserved
to avoid breaking changes.

Resolves #157
