Fix single note query

[dcadenas]

This fix involves converting the passed ID to binary before using it in the SQL query to ensure proper handling of BLOB data types.

I also removed the unnecessary settings that were added to the connection file, as they are not needed.

Covers #4

This can be tested by running a relay with docker compose up --build, fetching any id and then trying:
nak req -i $ID --force-pre-auth --sec $PERSONAL_SEC_KEY ws://localhost:8000

This works for me. I think I found another bug on auth_changes though: I tried turning off nip-42 auth in the config.toml but it still requires authentication for publishing new events.

Have you considered contributing this back upstream? At least the changes to sqlite.rs?

I didn't pay much attention about usages not mapped to the olympics relay use case but I'll add what you found to the draft PR that deals with cleanups and tests. Maybe one day we can contribute with that once we are sure it's works nice for a generic solution.

I had added scsibug#201 to contribute with this current fix.
