Drop fast input sorting: doesn't work on multiple pages in current implementation, and not scalable if done in MySQL. Instead, provide a way to filter by cash container reference.
Translate error messages.
Stop caching values inside script. To be added back if current code is demonstrated to benefit from it.

Also, factorise forms, fixing divergences:
- always display reception date
- fix price display
- fix quantity display
- always check a start date is set
