[wakonig]

Description

Rename Name/Entry to Device/Signal for consistency.

[Copilot]

Pull request overview

Updates the CurveTree table headers in the waveform curve settings UI to use clearer terminology that matches the underlying device/signal selection widgets.

Changes:

• Renamed CurveTree column headers from “Name”/“Entry” to “Device”/“Signal”.

            ["Actions", "Device", "Signal", "Scan #", "Color", "Style", "Width", "Symbol"]

        header = self.tree.header()
        for idx in range(self.tree.columnCount()):
