fix: pre-launch UI hardening + KOL reduce-action type, proxy IP relay, settings redesign

Frontend half of the pre-launch audit campaign:

- types/index.ts + kol/KolPageClient.tsx: add missing 'reduce' KolAction
  (backend emits it; frontend lacked the type + color/label maps → undefined
  styling). Adds ACTION_COLOR/actionLabel/postActionLabel entries.
- proxy/[...path]/route.ts: relay real client IP (x-forwarded-for / x-real-ip)
  so the backend rate limiter buckets per-user instead of per-Next-server (BUG-02).
- Settings/BotConfigPanel redesign, paper-mode clarity, copy cleanup.
- Assorted page/display fixes, loading states, Pagination component.
