Refactor document versioning to extract fields from uploaded .docx files on the server side

- Removed the `fields` parameter from the version upload form, as it is now extracted from the uploaded .docx file using the `extractContentControls` function.
- Updated related types and interfaces to reflect the new structure of version fields.
- Modified the OpenAPI specification to document the changes in the versioning process.
- Adjusted tests to ensure compliance with the new behavior, including validation for the absence of the `fields` parameter.
- Implemented a new function `extractDocumentSnapshot` to handle the extraction of content controls and document properties from .docx files.
- Updated metadata and versioning services to align with the new extraction logic.
