274: single-spine route shapes, west and east approach stubs

The route shapes were built by sorting road nodes by distance. Where R274 has a
central reservation OSM draws each carriageway as its own way, so the sort
alternated between them: 216 of 1,715 points in 274-route.json lay on the second
carriageway, up to 38 m sideways, in the divided sections after 福山大橋 and
through 占冠. All three shapes are now traced back along the shortest-path tree,
so they follow one spine. Point spacing sums to exactly the km span and km
strictly increases in every file. No roster coordinate came from a dropped point.

  274-route-west.json   54 pts   30.46 -  35.53  ends on the first main point
  274-route.json      1499 pts   35.53 - 108.74
  274-route-east.json   54 pts  108.56 - 113.99  overlaps main by 0.18 km

The stubs let the video bring the road in before 川端橋 and carry it on past
右左府 for 東に続く. The GeoJSON carries all three as separate lines.

Page and GeoJSON rebuilt, which also picks up the roster fixes. 274-dev.md
brought up to date: file table, current roster figures, and three new entries
under errors found and fixed.
