Budget Alerts and Notifications

[mohit-nagaraj]

Todo:

• Database Schema Changes: Add fields to store budget limits and alert thresholds for different expense categories.
• API Changes: Create endpoints to set, update, and retrieve budget limits and alert thresholds.
• Notification System: Implement a notification system to alert users when they approach or exceed their budget limits. This could include email notifications, in-app alerts, or push notifications.
• UI Changes: Allow users to set and manage budget limits and alert thresholds through the frontend. Display alerts and notifications to users when their spending approaches or exceeds their set limits.
