Automatically generate the pre-filter query from extraction fields

[medihack]

Automate the query generation using the user-defined data extraction fields. This can be used in the "extractions" and "subscriptions" features.

Workflow:

1. The user defines the extraction fields and creates the job.
2. The fields are automatically converted into an appropriate query by an LLM.
3. This query is then used to pre-filter the reports.
4. The pre-filtered reports are sent one by one to the LLM for data extraction (as before).
