chore: apply cargo fmt and fix clippy warnings

Fix pre-existing clippy lints:
- &PathBuf -> &Path in audit_cleanup.rs
- too_many_arguments on process_newly_available_git_data,
  process_purgatory_announcements, and HttpService::new
- clone_on_copy for PublicKey (Copy type) in purgatory cleanup loop
