Consolidate project linting into tool scripts.

The new `tools/check-lint` script checks lints across _all_ lintable files - JS (through `eslint`), and Rust (through `clippy` and `cargo check`). It also checks `eslint` against the whole project, not just against what's in the `ui` subdir, which means it now catches lintable issues in various JS config files.
