content(wiki): purge v0.1 Sova/Van Maanen residue (#865)

Spring-cleaning accumulated v0.1 vertical-slice residue across the
wiki. Scope per Jeroen's pre-decisions on 2026-04-21:

- Delete outright: wiki/star-systems/GJ-35/sova/ subtree (5 files +
  2 dirs) — v0.1 Station Sova / Transit District content.
- Strip example blocks in authoring guides and _templates/ that
  cited dropped v0.1 NPCs (Kael Davan, Sera Venn, Nils Davan, Devra,
  Torek, Renn, Pell, Tav, Lera Sessik, Sabel). Replaced with short
  "v0.1 examples removed — D-122" notes pointing authors to the
  active NPC roster.
- Rewrite canonical-lore references file-by-file: faction pages,
  technology pages, contraband pages, concepts pages, corp pages
  that cited v0.1 names/places. Preserve institutional/structural
  content, drop specific-name citations.
- Commission name drift: replace "Concord Commission" and "Assembly
  Commission" with "the Lattice Commission" (D-193) throughout.
- Van Maanen's Star cultural references: the canonical in-game name
  is Vuurkloof. "Van Maanen's Star" is retained only as an
  astronomical designation (glossary + GJ-35 Calibration Note).
  All cultural/system references converted to Vuurkloof across
  culture-authoring-guide, cultural-generation-guide, founder-gates,
  and star-system adjacent-system descriptions.
- Strip `v0.1` from faction/triangle frontmatter tags (8 files).
- wiki/triangles/hub-power.md and wiki/factions/the-ring.md:
  rewritten using role-name exemplars (Ring Coordinator / Shift
  Supervisor / THE FRIEND) instead of named v0.1 NPCs. Triangle
  pattern preserved as a structural reference.

Also applies drive-by Commission drift fixes and minor cross-ref
updates to canonical corps (gate-corporation, mastroianni-vehicle-group,
stalownia-kowalski, prometheus-labs, ferreira-monteiro, vins-de-grand-vide,
and 13 others).
