Restore center-pane borders, move title to top-left slot

- Current pane gets muted left/right borders only (no full box, no accent
  ring); border colors are passed only when a border is requested, since
  opentui flips borderless boxes to bordered when borderColor is supplied.
- Remove the Up / <current tab> / Detail titles above the panes; the current
  pane's title now renders once, top-left in the parent column's header slot.
- Drop the parentLabel/previewLabel props from PaneRow and all callers.
- Remove the tab/depth indicator from the bottom-left of the status bar.
- Tests measure column widths from the border glyphs and assert the
  left/right edges render muted regardless of focus.
