refine InlineError, ServerCard, HistoryEntry, and LoggingScreen

- InlineError: show more/less toggle on same line as message, collapsible
  details, doc link as button
- ServerCard: use ContentViewer with CopyButton for command, remove
  onCopyCommand prop, combine action rows, add responsive Card variant
- HistoryEntry: use ContentViewer with CopyButton for JSON blocks, swap
  duration and status badge positions
- LoggingScreen: stretch log stream panel to full height, center empty
  message vertically
