- Add "Online Notify" 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 to notification keywords
- Implement ExtractFirstIPFromMessage() for dependency-free IPv4 parsing
with per-segment 0-255 validation, handling diverse log message formats
- Extend NotifyManager::ShouldNotify with IP column (ONLINELIST_IP)
fallback check, ensuring IP keywords match regardless of the user's
configured ColumnIndex setting
- OnMsglogLoginNotify only appends keywords and enables the rule without
overwriting the user's existing ColumnIndex or TriggerType settings
- Menu item is automatically grayed out when PowerShell is unavailable
or no log entry is selected
- Sync en_US / zh_TW language files with new translation strings
