feat: Always show stop buttons when positions exist to prevent automation triggers

Modified Stop Button Logic:
- Stop buttons now visible when positions exist (not just when automation active)
- Prevents automation from triggering when positions close
- Added helpful tooltips explaining button purpose in different states

 Enhanced Button Behavior:
- When automation active: 'STOP' button stops running automation
- When positions exist but automation inactive: 'DISABLE' button prevents triggers
- Emergency button always available for immediate safety

 Safety Scripts Added:
- immediate-stop.js: Quick script to disable automation before position close
- Verifies position status and ensures no automation triggers

 Position Safety: CONFIRMED
- Current position: SOL-PERP LONG .41 PnL
- Automation: DISABLED ✅
- Safe to close position manually without triggering new automation

Critical for position management - stops automation from auto-triggering on position close.
