Description
**Describe the bug**
When multiple addplots exists in a panel, their label overlaps.
**To Reproduce**
```python
data["col1"] = np.random.rand(len(data))
data["col2"] = np.random.rand(len(data))
addplots = [
mpf.make_addplot(data["col1"], label="col1", panel=1),
mpf.make_addplot(data["col2"], label="col2", panel=1)
]
mpf.plot(data, type="candle", addplot=addplots)
```
**Expected behavior**
legends should be vertical stacked
**Screenshots**
**Additional context**
if panel=0, it's all ok.

Research direction
Start by running the Python reproduction from the issue with two addplots on panel 1, then trace mplfinance's panel legend handling. Done means the labels for multiple addplots in a nonzero panel render as a vertical stack without overlap, while the existing panel 0 behavior remains correct.
