Refactor UI state management (#1191)

* Added logs at generation of the UI, and generate the UI in an object
* Make ingest script more verbose in case of an error at ingestion time
* Removed the explicit state in the UI containing ingested files
* Make script of ingestion a bit more verbose by displaying stack traces
* Change the browser tab title of privateGPT ui to `My Private GPT`
