[FIX] web: unselect all list controller alignment

=== ISSUE ===

If you navigate to Project > Task > Gantt view > magnifying glass
and select some items, the arrow inside the `unselect all` component
is not aligned with the text.

This is due to the fact that the `.oi-large`
class uses a CSS variable called `--oi-vertical-align` which aligns the
icon a little bit under the middle.

=== AFTER ===

We add a `.align-text-bottom` class to the icon in order to align
the icon with its label.
