fix: dual bot token auth + P2P UI logic fixes

- All 17 edge functions now check both TELEGRAM_BOT_TOKEN and
  TELEGRAM_BOT_TOKEN_KRD for session verification
- Add perPage:1000 to listUsers calls to prevent pagination issues
- Fix offer button label: Buy tab shows "Al" (green), Sell tab shows "Sat" (red)
- Fix active tab highlight with cyan color for visibility
- Fix modal transparency (add --card CSS variable)
- Fix withdraw tab sync (useEffect on modal open)
