Apply incidental style tweaks

I kept these separate from the parent commit for clarity:

- Prefer trailing commas everywhere.
- Sort exported types alphabetically within groups.
- Use object short notation.
- Prefer idiomatic `== null` check over explicit `=== null` and `===
  undefined.
- (Subjective) use a ternary in one place where it doesn't harm
  readability.
