The action cluster (Test Connection / Use / Delete) had `flex-shrink: 0`
and the parent flex row had no `flex-wrap`, so on narrower Settings
panes the buttons spilled past the card's right edge instead of
flowing under the server info. Enable `flex-wrap: wrap` on the parent
and pin the actions with `margin-left: auto` so they stay right-aligned
when they wrap to a new line.
