Subject: [PATCH] feat(hikes): forgiving map selection, photo lightbox, detail
 polish

Map interaction:
- Overview map: widen the canvas renderer hit-test (tolerance) so a route
  can be hovered/clicked from a comfortable margin instead of demanding a
  pixel-perfect click on the thin line.
- Detail map: drive the elevation cursor from a whole-map mousemove that
  snaps to the nearest track point within ~70 px (track cached in
  layer-point space, refreshed on zoom/move), instead of requiring the
  pointer to ride exactly on the trail. The hover pin now renders for
  map-sourced hovers too, and is recoloured to nord red as a distinct
  "you are here" marker. Trail polyline made non-interactive.

Detail page:
- Move the photo strip above the stats row and trim it (3:2 cards).
- Add a fullscreen lightbox: an expand button on each card opens the
  full-res image with prev/next, arrow keys, Esc, backdrop-close and a
  body-scroll lock; opening/stepping syncs the map + strip. The card's
  existing click (map-position sync) is preserved.
- Cap inline prose images at 680 px (centered) so they don't blow up to
  full width in the single-column layout on wider screens; the desktop
  two-column layout is unaffected.
