[FIX] web: time picker should always be LTR

Steps to reproduce:
1-set language to an LTR language (arabic / hebrew...)
2-select any field with the date-time range widget (eg: planning>add)
3-the hour and the minute selection is reversed.

Bug:
the hours and minutes order depends on the language orientation where
they should always follow this format HH:MM

Fix:
force the time to be displayed Left To Right regardless of language
