fix: resolve clippy lints for CI

- Remove needless borrows in prompt_templates.rs few_shot_examples()
- Use push('\n') instead of push_str("\n")
- Remove duplicated #[cfg] attributes in neo4j_kb.rs and redis.rs
- Use struct initialization with ..Default::default() in redis.rs
- Replace match with if let for single pattern matches in completions.rs
- Use !is_empty() instead of len() > 0
