[FIX] account: fix searchpanel width issue

This commit fixes an issue about the search panel content being cut in
some accounting interfaces. This is due to the fact that the searchpanel
with a specific class would get an arbitrary width value in px.

To avoid this issue, we set a `w-auto` to the searchpanel, allowing it
to adapt its width to its content.
