Implemented datastore shared memory codebase

Changes:
- Added SharedMemory module for file-backed memory-mapped storage
- Added MappingInfo, FileHeader, RecordState and TrackedRecord infrastructure
- Replaced CSV-based serialization with binary struct serialization
- Added DataStore initialization and shutdown lifecycle management
- Added datastore mutex synchronization for multi-process access
- Added shared-memory mapping configuration for all datastore entities
- Added generic loadRecords and saveRecords template infrastructure
- Added automatic datastore directory creation and .dat file storage
- Updated configuration to use binary datastore files and initial capacities
- Added enum underlying types for serialization compatibility
- Added password masking support for login, registration and password change flows
- Added Visual Studio project configuration for shared-memory components
- Added datastore-owned record caches for runtime object management
- Updated datastore APIs to return cached tracked-record collections by reference
- Added generic cache refresh and cleanup infrastructure
- Updated save operations to persist datastore caches directly
- Added automatic cache cleanup during datastore destruction
- Prepared datastore for multi-process shared-memory persistence
