Adds the cnHeat-style horizontal 'Min RSSI' slider beside the opacity control. Pixels weaker than the threshold turn fully transparent, client-side, with no server round-trip — same compute output now powers an interactive 'where can I get -75 dBm or better' exploration. - Slider range -100..-40 dBm step 1; -100 disables filtering. - addCoverageLayer fetches each PNG into a hidden canvas and caches its ImageData. crossOrigin=anonymous keeps reads tainted-free. - Each pixel is classified by nearest palette colour (-50/-65/-75/ -85/-95 dBm centres matching Raster.write/3) and dropped if its dBm is below the threshold. Result re-encoded via toDataURL and swapped onto the L.imageOverlay via setUrl. - destroyed() revokes blob URLs and clears the filter cache to avoid leaks during LiveView nav.
