Text-to-SQL proof of concept (#5788)

Added:
- An "Ask AI" command to the command menu.
- A simple GraphQL resolver that converts the user's question into a
relevant SQL query using an LLM, runs the query, and returns the result.

No security concerns have been addressed, this is only a
proof-of-concept and not intended to be enabled in production.

All changes are behind a feature flag called `IS_ASK_AI_ENABLED`.
