Stockalyze Update: Point and Figure chart improvements and portfolio integration

[Sacha]

### Stockalyze Update — P&F improvements and portfolio integration

A new update to Stockalyze includes several improvements, with some significant work around **Point & Figure charts**.

**📊 Better Point & Figure charts for high-value instruments**

The P&F tier scaling has been improved for high-value instruments, making the chart much more meaningful across a wider range of prices.

This is particularly useful for instruments where other P&F charting tools can struggle. For example, **`^MERV`** cannot be plotted as a Point & Figure chart on StockCharts.com, while Stockalyze can create a meaningful P&F chart for it.

Another interesting example is the **Dow Jones Industrial Average (`^DJI`)**. The P&F chart in Stockalyze reveals meaningful patterns that are not apparent in the corresponding StockCharts.com chart.

These examples highlight one of the strengths of Stockalyze: **its P&F implementation is designed to work across a wide range of instruments and price levels**, while remaining highly interactive.

Other P&F improvements include:

* Current price is now marked on the P&F chart.
* P&F charts can now be used directly in the **Portfolio view**.

### Other improvements

* Transaction quantity and price fields now allow more decimal digits.
* Improved handling of price data in downloaded history containing empty fields.
* Simplified the Portfolio and Watchlist views.
* Improved chart window and event handling.
* Removed some unused India-specific symbols.
* Various fixes, cleanup, and code refactoring.

The Windows binaries are now signed with the new **Certum code-signing certificate**. So, it may happen you get a warning after download or during install. Please ignore those warning.

As always, please let us know if you find anything that needs fixing or if there is a charting feature you'd particularly like to see improved.
