📉 Remaining budget never goes negative, breaking UI logic

Description

The backend prevents negative values for remaining budget, but the UI expects them.

Issue

Backend:

remaining = max(0, monthly_budget - total_spent)

Frontend:

• Checks "remaining < 0" to show “over budget”

Impact

• UI condition for “over budget” never triggers
• Users are not informed when they exceed budget

Suggested Fix

• Remove "max(0, ...)", OR
• Update UI logic to match backend behavior
