lmr: dates aren't consistent between Origine and Sillon antérieur and create some weird behaviors

[axrolld]

What happened?

The available dates in the Origine datepicker are Sept 26th and 27th

But in the Sillon antérieur datepicker i can select Spetember 25th

And if i do so, the search is acting weird

The loader appears for less than a second then I get no error message.

What did you expect to happen?

I think matching the dates and not having Sept 25th here would fix the bug.

How can we reproduce it (as minimally and precisely as possible)?
