Refactor content decoders and restructure data layer

Updated `DocxContentDecoder`, `PdfContentDecoder`, and `TextContentDecoder` to return `Task<IEnumerable<Chunk>>` instead of `Task<string>`, introducing a new `Chunk` record for structured output. Restructured the `ApplicationDbContext`, `Document`, and `DocumentChunk` classes by moving them to the `SqlDatabaseVectorSearch.Data` namespace for better organization. Updated database migration files to align with the new entity structure and modified references in `Program.cs`, `DocumentService.cs`, and `VectorSearchService.cs` to use the new namespace.
