docs: wiki drift audit — fix stale counts, flags, viz/MapLibre, dep forks
Audited all wiki pages against current qsv source (v21.1.0):
- Command counts, version strings, stats/vocab/token counts corrected
- Removed non-existent flags (diff --select, fetch --redis-cache-conn,
QSV_TMPDIR, QSV_MEMORY_HEADROOM_MB) and fictional apply ops (cast,
wkt_point) / luau helpers; fixed luau col[] access + positional script arg
- viz page migrated Mapbox->MapLibre (DensityMap, token-free --style list,
--dict-info/--dataset-pid/--cluster/--heatmap-density)
- Security page dep-fork updates (csvlens YS-L, calamine/plotly/spreadsheet-ods),
geoconvert formats, validate keywords, Integrations release URL
- Recipe fixes: template arg order, Tieske date TAT, joinp --asof, --language

Add Security & Dependency Audits page
Document the daily cargo audit (security-audit.yml + .cargo/audit.toml),
the patched-fork strategy (including the sled fork that drops unmaintained
instant + fxhash), and the current vetted ignore list for unmaintained
transitive-dep advisories. Link from the Tuning & Internals sidebar.
