MTF EMA Directional Bias -1hr and 4hr

A compact, fixed-position table (bottom-right corner) that shows the current slope direction of two higher-timeframe EMAs:

4H EMA 50 → direction over the last 2 bars (UP ↑, DOWN ↓, or FLAT ⏸)
1H EMA 21 → direction over the last 2 bars (UP ↑, DOWN ↓, or FLAT ⏸)

Background color logic:

Green → both 4H and 1H EMAs are sloping upward
Red → both 4H and 1H EMAs are sloping downward
Gray → mixed or flat directions (no confluence)

Additionally draws the actual 1H EMA-21 (purple) and 4H EMA-50 (red) as step-lines on the chart.
