chore(highscores): align dependency and lint standards

Update the high-score service to the latest compatible direct releases while
keeping the requested Cargo.toml ranges: 0.x crates use their latest minor
line and 1.x crates use their major-only range. Refresh the standalone lockfile
so it resolves axum 0.8.9, rusqlite 0.40.2, serde 1.0.229, serde_json 1.0.151,
Tokio 1.53.1, and the latest dev-tool releases.

Copy the main package's Clippy policy and make the repository's formatting
recipes cover the service. The nested crate inherits the parent rustfmt.toml,
so one configuration remains authoritative; newly required documentation and
borrow style also keep the stricter pedantic policy clean.

Test Plan:
- `cargo update --manifest-path highscore-server/Cargo.toml` -- passed
- `just test` -- passed (3 service tests and 137 game tests)
- `just clippy` -- passed with the shared lint policy
- `just fmt-highscore-server` and `cargo +nightly fmt --manifest-path highscore-server/Cargo.toml -- --check` -- passed
- `cargo tree --manifest-path highscore-server/Cargo.toml --depth 1` -- confirmed latest direct resolutions
- `rustfmt +nightly --print-config current` -- confirmed the parent rustfmt settings
- `rumdl check --flavor commonmark highscore-server/README.md` -- passed
- `git diff --cached --check` -- passed
