address the final review of the voice outline fixes

- A building word ("Burj Khalifa Tower", "Sagrada Familia Church") passes
  the last-word rule on a building-like result; enclosures stay out.
- The anchor chooses only among the best-named outlines, so a worse name
  never wins by containment alone.
- An ask without a quadrant takes only the quadrant of the matching street
  nearest the point; a leading quadrant ("SE Main St") may go unsaid too.
- On an unbuffered tile edge a fragment shows as an edge along the
  boundary, so a whole building touching it at a corner is not cut.
- Drop two orphaned comments and correct the place-name key wording.
