Description

We currently have several snapshots embedded in the code of linera-witty-macros. insta is a tool for managing snapshots so that they don't clutter up the code and can be easily reviewed and regenerated that we are now using in linera-views-derive. It would be nice to use it for linera-witty-macros as well.

Research direction
Examine the existing snapshot tests embedded in `linera witty macros` code, then look at how `linera views derive` uses `insta` as a reference. The task is to replace the inline snapshots with `insta` snapshot calls, ensuring tests still pass and snapshots are managed via the `insta` review workflow.
