Fix Rust clippy lints for manual is_multiple_of and io::Error::other

[Copilot]

CI was failing due to new Rust 1.92.0 clippy lints triggered by the CVE dependency updates.

Changes

• Replace manual modulo checks with is_multiple_of(): Updated 4 locations in src/main.rs and src/neo4j_client.rs where count % N == 0 was used for progress logging
• Modernize error construction: Replaced io::Error::new(std::io::ErrorKind::Other, msg) with io::Error::other(msg) in src/utils.rs

// Before
if counter % 1000 == 0 {
    info!("processed {} queries", counter);
}

// After
if counter.is_multiple_of(1000) {
    info!("processed {} queries", counter);
}

These are idiomatic improvements with no functional changes.
