nice. can you fix CI and show how does it look with actual benchmarks? you can generate results to present by starting server via target/debug/iggy-server --fresh --with-default-root-credentials and in other shell target/debug/iggy-bench pp tcp output

also, please use precommit hooks + bump dashboard version to 0.5.0 in Cargo.toml so it's reflected in footer
