fix: continuous top border on status bar tabs, baseline alignment, 15% taller

- ViewTabButton always paints 1px top border matching status bar hairline;
  selected tab's accent line paints over it
- Remove SegmentedContainer (caused gap on unselected tab)
- Shared baseline alignment between tab text and status label
- Status bar height * 1.15
