fix: position inactive heaven beads above reckoning bar, not below

My previous attempt to match earth bead gaps exactly resulted in
inactive heaven beads appearing below the reckoning bar at 27pt
while the bar is at 20pt.

Fixed by:
- Positioning inactive heaven beads at bead-size/2 + 3pt = 9pt from top
- This places them clearly above the reckoning bar (at 20pt)
- Removed unused inactive-bead-gap variable
- Active heaven beads remain just above the bar as intended
