Livetable date range picker hour/minute selects are too wide and the selected date is not applied anymore

Steps to reproduce:

1. Go to the page index
2. Click in the date filter input
3. Click on "custom range"
4. Click on "apply"

Expected result:

The table is filtered by the selected date range.

Actual result:

No filtering happens.

This is a regression introduced by XWIKI-16150 as the date range picker is now a child of the table cell and there are styles from Livetable applied.

Further, the selector for selecting the hidden input in the code no longer works because the two inputs are no longer sibling elements.
