feat(outlines): restore voice outlines without public Overpass

use bundled place boundaries and shared OpenFreeMap tiles before a guarded Nominatim fallback

preserve multipart shapes, holes and cancellation,
and keep pending annotations visible while ground sampling finishes across frames

keep non-Latin name distinctions when selecting provider results,
and retain an outline anchor only when it lies in filled geometry
