fix(admin): stop a long action name printing over the activity row beside it

The dashboard renders an activity row action in a fixed `width: 110` span with
`flex: none` and no overflow handling, so a name wider than that overflows its
box and prints on top of the detail text next to it.

Core own actions all fit. A module one need not: `module-rust` writes
`rust.account.unlink.staff` when staff sever a player Steam link, and it
overlapped `steamId: …` on a live dashboard. `module-uo` `uoLink.account.link`
is already close to the edge.

`minWidth` instead of `width` keeps the column aligned for every short name and
lets a longer one push the detail right rather than sit under it. One property,
verified in a browser with both rows on screen.

Found while walking module-rust phase 6; raised here rather than worked around
there, because a module may legitimately name an action and shortening one
module names only moves the ceiling to the next one.
