Summary
Harden operational security for the web portal + API path used by EVM / Terra Classic signing:
/update_terms(stop unauthenticated sync triggers).ADMIN_TOKEN.redirect_urion the portal (and SDK helpers as needed).X-Forwarded-Forfor rate limiting.Bundle rationale: These are tightly related abuse/control-plane issues from
gaps/GAP_1786322222.mdaffecting the same deploy surface.Out of scope: Telegram/Solana crypto fixes, bot kick semantics, property auto-upsert allowlisting (can be follow-ups).
