feat: add repository layer with IUnitOfWork and fixed EF base

- ITransaction, IUnitOfWork in DAL.Abstract - EfTransactionAdapter, EfUnitOfWork<TDbContext>, NotificationUnitOfWork in DAL.EF - NotificationEfRepository<TEntity>: async-only base, fixed Exists (AnyAsync), fixed batch Add (AddRangeAsync), single SaveChangesAsync per operation - TemplateRepository, ProviderRepository, ProviderUsageRepository - ProviderUsageRepository.IncrementAsync uses atomic PostgreSQL upsert - ProviderRepository deserializes settings polymorphically via ProviderType discriminator Ref: IT-628 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
