input_datetime entity row: UoMs are started to be displayed, please hide

[ildar170975]

Starting from some recent HA update, these "hh" & "mm" labels are displayed:

I missed a moment (& a particular PR) when this was added.
Consider NOT to display them as it was before.

tbh, both workarounds cant hold, this is way too complex.

Suppose we should really put forward the FR to add a 'no units' option for these cards.

or, maybe another thought:
show the units inside the fields, to indicate to the user what to enter where, but when these fields are filled, the 'preview unit' is overwritten by the actual data entry.

Much like the 'name field itself of entities (so not the unit field here...):

suggestion based on template data

overwrite name with actual data

same could be done with date fields, and keep bot sides happy ;-)

lastly, please at least make this look better:

the formatting is so rough and ugly, wrong font, too small, not outlined correctly etc.
