Updated API and data retrieval methods for weekly statistics

Updated the API.http file and various methods across multiple files to include a toDate parameter for better data retrieval. This includes updates to GetWeeklyStatistics, GetStatisticsFrom, and CreatedFrom methods in OtherEndpoint.cs, IOtherService, OtherService, UnitOfWorkExtensions.cs, and repository files. The StatisticsModel and WeeklyDataModel records were also updated to accommodate these changes. Added a TotalCount method to the IProjectRepository.cs, IProjectResourceRepository.cs, and IUserRepository.cs interfaces and their respective classes.
