[fix] Location-Based Promotional Messaging

[wangchongyu]

When the user enters a predefined range (e.g., within 20 meters) of a specific location, the system detects that the user is near the targeted area. Upon detecting that the user is within this range:

AI sends a promotional message relevant to that location:

Scenario A: If the user currently has the AI chatbot dialogue window closed:

• The system displays a notification bubble to prompt the user to click and view the promotional message.
• The bubble serves as a visual cue, once the user clicks the bubble and opens the dialogue window to check the message, removes the bubble automatically

Scenario B: If the user already has the AI chatbot dialogue window open:

• The system sends the promotional message directly in the dialogue window.
• there is no need to display an additional bubble.
