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.
Updated the copy confirmation feature in `Ask.razor` by replacing the `isCopied` variable with `showCopyConfirmation`, improving user feedback with a longer display duration for the checkmark icon.

This update introduces a new feature that allows users to copy messages to the clipboard. A boolean variable `isCopied` tracks the copy action status, and the button now shows a check icon upon successful copy, reverting after 1.5 seconds. A null check is also added in the `CopyToClipboardAsync` method to enhance error handling.
