[FIX] web: FieldFloatToggle cell multi language

Have a timesheet uom per Day
Have a language with a different number format than English

Click on grid cell to change its value

Before this commit, the value was stuck on the highest value in range
This was because the parsing of the value into float was not taking into account
the real format of the float

After this commit, it works in all languages
