Member and collaborator names are cut off at half the sidebar width #3921

Bug Description

In the space members panel and the file share panel, member and collaborator names are truncated at about half the row width, with free space to their right and no tooltip. web-app-files/src/components/SideBar/Shares/Collaborators/ListItem.vue:8 uses grid-cols-2, so the name column only gets half the row.

Fix: let the name column take the remaining space (e.g. grid-cols-[1fr_auto]) and show the full name as a tooltip when it is truncated.

Reproduction Steps

1. Share a file or space with a user whose display name is long (e.g. 40 characters).
2. Open the share panel of the file or the members panel of the space at desktop width.

Expected Outcome

The name uses the row up to the actions on the right; a truncated name shows the full name on hover.

Actual Outcome

The name is cut off at half the row width, look-alike names can't be told apart.
