chore: fix and reduce clippy allows in knowledge_entity.rs

- rm duplicate 'document' match arm (match_same_arms)
- .get(0) -> .first() (get_first)
- for entity in all_entities.iter() -> &all_entities (explicit_iter_loop)
- 2x error!("{}", err_msg) -> error!("{err_msg}") (uninlined_format_args)
- 2x test format!()/assert!() positional -> inlined (uninlined_format_args)
- removed 6 now-unnecessary allow attributes
