fix: v1.6.6 — InfraLens 404 page and privacy disclosure accuracy

- remove the redundant "Retour aux outils" link from InfraLens's 404 —
  ToolPageShell moved from the shared layout into each page individually
  so the 404 can skip it and keep a single, page-specific CTA
- correct that CTA's color — it used brand-secondary (blue), not
  brand-accent (InfraLens's actual green identity)
- correct the privacy page's rate-limiting disclosure: it's Upstash
  (Redis-backed, an external store) at 5 req/min + 30/h, not an in-memory
  counter at 1 req/30s, and Upstash is a second third-party service that
  does receive the visitor's IP — both previously undisclosed

+### Fixed
+
+- **InfraLens 404 page and privacy disclosure accuracy** — the 404 page
+  no longer shows a redundant "back to tools" link above its own CTA,
+  and that CTA now renders in InfraLens's actual green identity color
+  instead of blue. The privacy page's rate-limiting section now reflects
+  the real Upstash-backed policy (5 requests/minute, 30/hour, an external
+  store) instead of the pre-migration in-memory description, and
+  discloses Upstash as a second third-party service that receives the
+  visitor's IP.
