style(tui): breathing room around status glyphs in agents overlay

- List rows: pad the status dot with space before (heat-marker gap or
  matching 2-space filler) and after (3 spaces to goal) so `●` / `○` /
  `✓` / `■` / `✗` don't read glued to the heat bar or the goal text.
- Gantt rows: bump id→bar separator from 1 to 2 spaces; widen the id
  gutter from 4 to 5 cols and re-align the ruler lead to match.
