fix: auto-refresh using st_autorefresh JS timer instead of sleep/rerun

view_live_mt5_eas.py:
- Replace broken sleep+rerun approach with streamlit-autorefresh
  which injects a JS timer — works without user interaction
- Graceful fallback if package not installed, shows install hint
- First page load always pulls fresh data from FTP
- Auto-refresh fires FTP pull when poll interval has elapsed

requirements.txt:
- Added streamlit-autorefresh
