Implement Notification Trigger Mechanism [86-2 Notification Trigger Mechanisms & Services]

[VovaD199]

Description: Develop backend mechanisms that trigger notifications based on specific actions by an investor, such as following a startup's profile or sending a message.

Acceptance Criteria:

• Implement event listeners or hooks within the application that detect when an investor follows a profile or sends a message.
• Upon detecting such events, a notification record should be created in the database.
• Ensure that the notification mechanism is efficient and does not introduce significant latency to the investor's actions.
