pd review: document the new columns, pin the coverage notion, drop dead code ...

Third review pass over the blend material.

Completeness:
- the simulator README documented neither frac_reached_live nor the three
  correlated-churn columns (churn_mode, n_regions, region_locality) that every
  run now writes, and its model section never described correlated outages at all;
- the knowledge graph had no pd nodes -- graphify update had never been run since
  the simulator was added (2643 -> 2968 nodes).

Correctness/coherence:
- section 3.5 quotes coverage without saying which coverage, now that 3.9
  distinguishes all-node from live-network. It is all-node; under uniform churn
  the two agree to 0.001, so nothing in 3.5 turns on it. Said so explicitly;
- 3.9 named its groups AS/region without noting that link latency ignores them.
  Regions are failure and peering domains, not latency domains -- real co-located
  nodes would also be faster, so the clustered delays are if anything pessimistic.

Redundancy:
- style.band_plot was dead: never called by any figure. Removed, with the two
  imports it alone needed;
- the units sentence appeared verbatim in the header note and again opening the
  model section. Dropped the second.
