style: clear the lint and prettier findings so the gates pass

- prettier formatting across routes, components and tests (no behavior change)
- unused imports and ternary-as-statement replaced with explicit branches
- eslint: scripts/**/*.js are CommonJS, allow require() there; prettier ignores pnpm-lock.yaml
