Describe the bug

Setting localisation like this:

Task settings like this:

Results in Invoice-Details like this (should be "2,25 Stunden" instead of "2.2500 Stunden") wrong decimal-separator, too many decimals:

Steps To Reproduce

setup like screenshots above

Expected Behavior

Formatting should be e.g "2,25 Stunden" instead of "2.2500 Stunden"

Additional context

The react backend has no option to influence this behaviour probably (see flutter backend):

The Linux App of which I guess is flutter-based works also not as expected – and not stable enough (Ubuntu 24.04.1 LTS, IN 5.0.158). It delivers mixed results:

@Civolilah please ensure client localized number formatting for the duration of task

Thank you, @turbo124
the localized formatting should also work in "Reports" section (Screenshots).
This formatting issue leads to difficulties in number recognition e.g. here in latest LibreOffice. The Item description should contain the clean Text – not the markup-Version. Therefore the CSV gets really heavy to clean out. What do you think?

@Civolilah

The preview should provide a formatted export matching the company currency

@cdahinten are you able to create this as a separate issue so we can track these separately please?
