Standardize chart save/export filenames between Dashboard and Lite

[erikdarlingdata]

Problem

The two apps use completely different approaches for chart right-click save/export filenames:

Dashboard (Dashboard/Helpers/TabHelpers.cs – SetupChartContextMenu):

• Custom context menu with descriptive, structured filenames
• PNG: {chartName}_{yyyy-MM-dd_HH-mm-ss}.png — e.g. UserDB_Read_Throughput_2026-02-25_11-30-00.png
• CSV: {chartName}_data_{yyyy-MM-dd_HH-mm-ss}.csv
• Includes chart title and data source info in the menu

Lite (no custom context menu):

• Falls through to ScottPlot's built-in right-click menu
• Default filename is just ScottPlot.png — no context, no timestamp, no chart identity

Expected Behavior

Lite should use the same ContextMenuHelper-based pattern as Dashboard, with descriptive filenames that include:

• A chart-specific name (e.g. cpu_usage, file_io_read_latency)
• A timestamp (yyyyMMdd_HHmmss — Lite's existing convention)

This would make saved exports identifiable without renaming them, matching Dashboard behavior.

Implementation Notes

• Lite already has Helpers/ContextMenuHelper.cs for CSV exports — a chart save method could live there
• Dashboard's SetupChartContextMenu in TabHelpers.cs is the reference implementation
• Lite uses yyyyMMdd_HHmmss format (e.g. alert_history_20260225_113000.csv) vs Dashboard's yyyy-MM-dd_HH-mm-ss — pick one and use it consistently
