Add a simple way to archive expenses

[thomas-bouvier]

Is your feature request related to a problem? Please describe.

Instead of deleting expenses when they are not active anymore, I would prefer to archive them. Archived expenses could have their own tab to find them back.

Describe the solution you'd like

A simple "Archive" button that would move an expense from the main tab to a new tab gathering archived expenses. A new field would probably be needed to save the date when the expense was archived.

Describe alternatives you've considered, if any
