Emi Griffith 4d3a5a1053 Convert the frontend to ES modules; split nav.js by concern (#48)
The frontend was classic scripts sharing one global scope, with a
load-order contract enforced only by comments (leaflet -> nav ->
shared -> mappicker -> page) and hand-rolled window.Thermograph /
window.LocationPicker namespaces. Page scripts now import what they use;
the dependency graph replaces the ordering contract, and no app globals
remain (Leaflet stays a classic script / global L, loaded first).

nav.js had grown four concerns; it's now three single-purpose modules:
- nav.js: last-location memory + header view-links + locHash.
- units.js: the °F/°C toggle and unit-aware formatting. The compare
  special case is gone — pages that want the toggle import units.js;
  compare simply doesn't.
- cache.js: the IndexedDB response cache, SWR getJSON, bundle-seeded
  view prefetch and neighbor warming. prefetchViews(lat, lon, ownViews)
  now takes the calling page's own view names instead of a page-identity
  map (VIEW_OWN) — adding a page no longer means editing this module.
  The slice->URL map stays here as bundle-contract knowledge.

frontend/package.json ({"type": "module"}) makes CI's node --check
parse the files as modules.

Verified: node --check on all files as modules; 108 backend tests;
headless-Chromium smoke across all five pages against live data — zero
console/page errors, all render assertions pass (cards, chart, calendar
grid + metric switch, ladders, compare ranking, legend scales).
