Make the driver page-lazy (it resolves the running test's page on demand via
an auto fixture) so it can be created a single time at describe scope and
reused across the block's tests, matching the pre-migration ergonomics:
const { given, get, when, then } = new MaputnikDriver();
instead of pulling `driver` out of a fixture and destructuring it in every
test. Coverage collection and dialog handling move into the auto fixture.
Also inject a bare invalid token ("zzz") in the json-editor parse-error test:
CodeMirror auto-closes brackets/quotes, so " {" no longer reliably breaks the
JSON.
