Jacquin Antoine c6c804749e Skip SharedDEM computation when all visualizations already exist
Two optimizations to avoid ~2min wasted per file on re-runs:

1. pipeline.py: Check which visualizations need regeneration before
   computing SharedDEM. If all WebP outputs exist, skip SharedDEM
   entirely. If only IGN overlays need updating, also skip SharedDEM.

2. visualizations.py: Make SharedDEM attributes lazy (filled, gradient,
   lrm_15) so only the data actually needed is computed. For example,
   if only hillshade is regenerated, LRM at 15m is never calculated.
