Replace the brand mark with the grid-cell logo everywhere (#199)

Swaps the stepped-path mark for the "C1 v2" design: an 8x8 grid of graded
day-cells tracing the same climb (blue Low -> green Normal -> a hot loop -> a
stepped ascent to the near-record red cell). It keeps the exact geometry of the
old mark — same 512 viewBox, same 32/448/rx96 rounded badge, same band palette —
so it is a drop-in that needs no alignment changes.

Everywhere the mark appears:
- The inline header SVG in all six lockups (the five standalone frontend pages
  and backend/templates/base.html.j2), kept at width/height 28 with aria-hidden.
  Because the box and viewBox are unchanged, the .logo/.brand alignment CSS
  (the -2px cap-height nudge, the 28->22px compact size, the 10px gap) is
  untouched and the mark stays centred on the "Thermograph" wordmark.
- favicon.svg, regenerated from the new art.
- Every raster: favicon-16/32/48, apple-touch-icon (180), logo-192, logo (512),
  and the two maskable icons. The maskable pair keeps the established recipe —
  the badge scaled into the central safe zone on a full-bleed opaque square — so
  an OS shape mask never clips the art.

Bumps every icon reference to ?v=3 (previously a mix of ?v=2 and unversioned) so
browsers and installed PWAs refetch the new icons.
