🔁 Budget model allows multiple entries but logic enforces single budget

Description

There is a mismatch between the database schema and application logic.

Issue

• "models.py": defines one-to-many relationship ("User.budgets")
• "app.py": deletes all existing budgets before inserting a new one

Impact

• Inconsistent design
• Potential confusion for future development

Suggested Fix

• Convert to one-to-one relationship, OR
• Allow multiple budgets and update logic accordingly
