Enhance Ingest Settings UI and functionality

- Added a new 'tableStructure' setting to the IngestSettings interface and UI.
- Updated the IngestSettings component to include a select input for the embedding model.
- Improved layout and accessibility of input fields and switches.
- Integrated default settings for chunk size, chunk overlap, OCR, picture descriptions, and embedding model from constants.
- Implemented synchronization of settings with backend data using React Query.
