Fix consistency bug, rename Random to Auto, add stop-after-all, direction pills, copy-trade

Bug fixes:
- Fix computeDailyTarget when consistency is 0% or 100%: treat as no constraint,
  letting min-day reservation or full remaining profit drive the target
- Rename 'Random' to 'Auto' across entire codebase (types, API, UI, scheduler)

Features:
- Add "Stop after all eligible" checkbox: auto-stops scheduler when all
  configured accounts are dead, inactive, already traded, or challenge complete
- Show position direction in status pill: "Long" (green) / "Short" (red)
  instead of generic "In Trade" (blue)
- Add "Copy to Max" button: copies current trade direction to remaining
  eligible accounts up to max_concurrent_accounts limit
