Fix ACARS contact + filtering, Fix Chat persistence + custom slur only filter

[1ceit]

This pull request introduces significant improvements to the chat system, focusing on enhanced hate speech detection and automoderation, improved mention handling, and better user experience in the chat UI. The main changes include replacing the basic profanity filter with a custom hate speech filter, updating how mentions are processed and stored, providing clearer automod feedback to users, and improving chat message loading and UI responsiveness.

Chat moderation and hate speech detection:

• Replaced the bad-words profanity filter with a custom hate speech filter (hateSpeechFilter.ts) that uses regular expressions to detect racial slurs and extremist content, and provides a specific reason for automoderation. The automod reason is now returned and displayed to the user. [1] [2] [3] [4] [5] [6]

Chat mention and active user handling:

• Mentions are now resolved to user IDs (not just usernames), and the backend stores and processes mentions as user IDs for accuracy. The chat system emits chatOpened and chatClosed events to more accurately track active users in a session, improving the active user indicator. [1] [2] [3] [4]

Chat UI and user experience improvements:

• The chat sidebar now tracks and displays specific automod reasons for flagged messages with a tooltip, improves error handling and feedback when loading messages, and implements smart auto-scroll behavior. Chat messages are loaded only once per session open, and the socket connection persists across chat UI open/close events for better performance. [1] [2] [3] [4] [5]

Flights websocket (controller contact):

• The contactMe event in the flights websocket now supports optional station and position fields, which are sanitized and included in both the request and emitted events, providing more context for controller/flight interactions. [1] [2] [3]

Other:

• Added some ASCII art comments for flavor in certain files. [1] [2]

These changes collectively enhance moderation accuracy, chat reliability, and the clarity of feedback provided to users.

The useMemo hook calls getDefaultMessage() which is a function that depends on frequencies, selectedPosition, and airportIcao, but getDefaultMessage itself is not stable (it's redefined on every render). This defeats the purpose of useMemo. Either include getDefaultMessage in the dependency array or inline the logic, or move getDefaultMessage outside the component or wrap it in useCallback.

Suggested change

	const getDefaultMessage = () => {
	const freq = frequencies.find((f) => f.type === selectedPosition);
	if (freq) {
	return `CONTACT ME ON ${airportIcao}_${selectedPosition} ${freq.freq}`;
	}
	return 'CONTACT ME ON FREQUENCY';
	};
	// Use useMemo to ensure consistent message evaluation
	const currentMessage = useMemo(() => {
	return customMessage.trim() || getDefaultMessage();
	// Use useMemo to ensure consistent message evaluation
