overdue-reminders

Help the user manage overdue invoices and send payment reminders:

Step 1: Find overdue invoices

• Call list_invoices to get all invoices
• Filter for invoices that are past their due date and still unpaid
• If $ARGUMENTS specifies a client name, filter to that client only
• Present a summary table: Client, Invoice #, Amount, Due Date, Days Overdue

Step 2: Prioritize

Group overdue invoices by severity:

• Gentle reminder (1-14 days overdue): First reminder, friendly tone
• Second reminder (15-30 days overdue): Firmer tone, reference original due date
• Final notice (30+ days overdue): Urgent, mention potential consequences

Step 3: Review before sending

For each overdue invoice (or batch per client):

• Show the invoice details: amount, due date, days overdue
• Show the client's contact info from get_client
• Let the user decide whether to send a reminder or skip
