beacon: add progress bar and milestone chips to phase bar

- Progress bar shows % toward next phase threshold based on totalCode
- Milestone chips show upcoming code milestones with pulse animation on next target
- Recently completed milestones shown with green checkmark
- All elements use the existing cyber-monastic aesthetic
