copy: rewrite site messaging to lead with design, temper infrastructure

Complete copy overhaul across all pages (EN + FR):
- Hero: "Your website. Your software. Your entire digital world."
- Services: "Design. Build. Grow." with reordered pillars
- Philosophy: "We do things differently" — craft leads, ownership closes
- About: remove all Côte d'Azur/Riviera references, new story narrative
- Services page: less jargon, outcome-focused language, honest AI claims
- SEO metadata: includes all three pillars (design, AI, infrastructure)
- Trust bar, CTA, footer, configurator, case study CTAs all updated
- French translations updated to match all English changes

-            We design, build, and operate complete digital ecosystems — from the
-            first pixel to the server rack. Every discipline under one roof,
-            every deliverable built to a standard most agencies never attempt.
+            We design custom websites, build purpose-built software, and manage
+            the infrastructure behind it all — one team, one standard of
+            quality, nothing outsourced.
