Replace Leaflet/raster tiles with MapLibre GL JS: an online OpenFreeMap style and an offline style built from a local PMTiles archive via pmtiles.js and protomaps-themes-base (no glyphs/labels offline by design, see docs/architecture.adoc). Frontend libraries are vendored locally rather than loaded from a CDN so the app keeps working with no internet access. Also add an animated RainViewer precipitation radar overlay (toggle, play/pause, scrub slider), matching the default time window of the weather-radar-card Home Assistant integration.
