Refactor extract_vector method to support multiple buffer types

- Added a private helper method `buffer_to_uint8_array` to convert various buffer types (Uint8Array, ArrayBuffer, string) to Uint8Array.
- Updated the `extract_vector` method to accept a wider range of input types and handle null values.
- Adjusted calls to `extract_vector` throughout the DatabaseManager class to remove type assertions for Uint8Array.
