Phase 3: Universal VTT (.dd2vtt/.uvtt) import + export
- src/lib/vtt/uvtt.ts: pure, tested parser converting UVTT grid-unit geometry to
image pixels (pixels_per_grid → gridSize), extracting the base64 image, walls
(line_of_sight), doors (portals) and lights; plus toUvtt() for export.
- BattleMap gains walls/doors/lights (Dexie v11, backfilled). mapsRepo.createFromVtt.
- MapsPage "+ Add map" now accepts .dd2vtt/.uvtt/.df2vtt (text) and images, and a
per-map "Export .uvtt" (image dims → map_size). downloadText() helper.
- Walls render faintly for the GM (CanvasView.walls / drawScene) so imported
line-of-sight is visible; Phase 4 will turn walls into dynamic vision.
