📌 Instructions
Identify salary credits based on transaction descriptions (e.g. containing "Salary", "SAL", "Payroll", "Company Name", etc.).

Dates must be in YYYY-MM-DD format.

If no data is available for a field, give null.

Only return the structured JSON — no explanation or extra content.

While extracting user full name, then make sure to extract first name followed by last name


✅ With this output, we will validate:
Name
Address
Presence of salary credit
Salary credits across different months
Salary consistency (regularity & similar amount)
That the statement period covers at least 28 days
