Archives an invoice, changing its status to 'archived'.

Archive Process

Archiving an invoice moves it out of the active workflow and prepares it
for potential deletion. Archived invoices are typically no longer needed
for day-to-day operations but are kept for record-keeping purposes.

Post-Archive Actions

After archiving, an invoice can be:

• Restored (by updating its status)
• Deleted (if it's no longer needed)
