Feature: Add "Ban IP" to log message context menu in main dialog

- Add "Ban IP" menu item to the log message list (m_CList_Message)
  right-click context menu, allowing users to extract IPv4 addresses from
  selected log entries and add them directly to the IP blacklist
- Reuses ExtractFirstIPFromMessage() from the previous commit for
  dependency-free IPv4 parsing with per-segment 0-255 validation
- Checks against whitelist before banning (whitelisted IPs cannot be
  banned) and skips IPs already in blacklist with clear feedback
- Immediately persists via THIS_CFG.SetStr to the config ini file;
  IPBlacklist singleton takes effect instantly — subsequent connections
  from banned IPs are rejected in IOCPServer::OnAccept() which already
  calls IsIPBlacklisted() on every new connection
- Menu item is grayed out when no log entry is selected
- Sync en_US / zh_TW language files with new translation strings
