fix(extension): remove the orphaned security-banner block; repair two dead CSS tokens

Design-review findings. The 197-line .security-banner component (incl. its
keyframes) had no producer — no JS has created the element since the
chat-path rip, the same dead-hidden-security-UI class as the #2557 shield
this wave removed; a tombstone comment points at git history if the banner
UX returns. Two pre-existing token bugs in the mem-toast styles: --zinc-700
was never defined so the button hover computed to transparent (now carries a
fallback), and --font-sans doesn't exist (now --font-system, which :root
defines).
