Marco Minerva 404cd7565a Switch to SqlVector<float> for embeddings
Updated the application to use SQL Server's native vector data type (`SqlVector<float>`) for embeddings, replacing the previous `float[]` or `string` representations.

- Updated `.editorconfig` with new code style preferences and diagnostic rule severities.
- Modified `DocumentChunk.cs` to use `SqlVector<float>` for the `Embedding` property.
- Updated migrations and `ApplicationDbContextModelSnapshot` to reflect the new `SqlVector<float>` type.
- Replaced `AddAzureSql` with `AddSqlServer` in `Program.cs` and removed `UseVectorSearch`.
- Adjusted `DocumentService` and `VectorSearchService` to handle `SqlVector<float>` and updated vector search logic.
- Removed the `EFCore.SqlServer.VectorSearch` package and upgraded EF Core to `10.0.0-rc.1`.
- Made minor adjustments to OpenAPI configuration and dependency management.
