Feat/109 status indicator update

I added an indicator status that krack whether a user is online or disconnected of a current session, as you can see on the image below (red for disconnected and green for connected). So, the logic is simple, I noticed that there is an attribut called is_active for each user which is true by default. So, when a user logs out, I turned this value to False. So, in Message.svelte, I handle the user status based on this attribut. But the issue is not yet ended up, I need to think how to handle the fact that a user is still connected but not present in the session. So, I was wondering about if I need to set a timer to track the inactivity of a user (e.g if a user didn't make an action during a while, I set its presence as inactive ?)

 import { type ServerLoad, redirect } from '@sveltejs/kit';
+import { patchUserAPI } from '$lib/api/users';
+
+export const load: ServerLoad = async ({ cookies, locals, fetch }) => {
+	if (locals.user) {
+		try {
+			const success = await patchUserAPI(fetch, locals.user.id, { is_active: false });
+			if (!success) {
+				console.error('Failed to update user status.');
+			}
+		} catch (error) {
+			console.error('Error updating user status:', error);
+		}
+	}
 
-export const load: ServerLoad = async ({ cookies }) => {
 	cookies.set('access_token_cookie', '', { maxAge: -1, path: '/' });
 	cookies.set('refresh_token_cookie', '', { maxAge: -1, path: '/' });
 
-	redirect(303, '/login');
+	locals.user = null;
+
+	throw redirect(303, '/login');
 };
