fix: real Max plan price — €100/mo (not $400) + corrected ~30× compression

Reality check: Stéphane pays €100/mo for Claude Max, not $400/mo.
Recalculated ratio: $6,770 PAYG over 59 days ≈ $3,440/mo equivalent
vs €100/mo (~$108) paid = ~30× compression factor (was 8×).

Affected:
- /claude (EN+FR) — economics cards
- /ia (EN+FR) — RTK methodology mention
- /making-of/v3 — shipped list
