feat(ui-lvgl): vector map spike (own VT2 format from OSM)

Browse Source 
tools/maps/osm_vector.py turns Overpass JSON into VT2 tiles (data zooms
10/12/14, per-feature bbox, simplified); VectorTileProvider draws them
into 256 px tiles (scanline polygons, thick lines with round joins) with
a small PSRAM cache of data files. Behind Map tools > Vector map (test),
raster where there is no vector data.
