Fix maps not rendering: Neshan SDK URL was a 404

The map script loaded https://static.neshan.org/sdk/leaflet/1.4.0/neshan-sdk/v1.0.8/index.js,
which Neshan has removed (returns 404) — so window.L never defined, the init bailed, and NO map
rendered anywhere (detail pages + the facility-register picker). Switch to Neshan''s current SDK
(.../1.4.0/leaflet.js + leaflet.css, both 200). The init API is unchanged (new L.Map with the
maptype option), so no other code changes needed.
