Fixes #3982. Add Draw trace category and instrument View.Drawing.cs

[Copilot]

Adds a Draw trace category to the tracing infrastructure and instruments the draw pipeline with Trace.Draw(...) calls, enabling diagnostic tracing for draw operations in DEBUG builds. Also adds UICatalog menu items for the Configuration and Draw trace categories.

Proposed Changes/Todos

• TraceCategory.cs — Draw = 64 added to [Flags] enum; All updated to include it
• Trace.cs — Trace.Draw(string? id, string phase, string? message = null, [CallerMemberName] string method = "") following the existing [Conditional("DEBUG")] / guard / Backend.Log pattern
• ApplicationImpl.Screen.cs — LayoutAndDraw: traced at Start (with forceRedraw) and End (with neededLayout/needsDraw)
• View.Drawing.cs — Static Draw(IEnumerable<View>, bool force): traces each view before its draw call; Instance Draw(DrawContext?): traces each phase — Start, Adornments, SubViews, Text, Content, LineCanvas, End
• TraceTests.cs — TraceCategory_Draw_HasExpectedValue, TraceCategory_All_IncludesDraw, Draw_Category_CanBeEnabled
• UICatalogRunnable.cs — Added Con_figuration and _Draw CheckBox menu items to the _Logging menu so both trace categories can be toggled at runtime

<issue_title>Add Draw trace category and instrument ConfigurationManager</issue_title>
<issue_description>## Summary

Add a Draw trace category to the tracing infrastructure and instrument View.Draw.cs with Trace.Draw(...) calls. This enables diagnostic tracing for all Draw-related operations (property discovery, source loading, property assignment, JSON deserialization errors).

Motivation

Draw is a complex subsystem

Trace.Draw should not be used for places where Logging.Error or Logging.Warnings are currently used (or commented out). Generally if there's a commented out Logging call in the Draw codepath, that's a good candidate for Trace.Draw but do not over-do it; too much trace noise is not a good thing.

Changes

TraceCategory.cs

• Add Draw= 64 to the [Flags] enum
• Update All to include Draw

Trace.cs

• Add Trace.Draw(string? id, string phase, string? message, ...) method following the existing pattern ([Conditional("DEBUG")], guard check, Backend.Log)

Terminal.Gui/Draw/ — Instrument key paths:

• LayoutAndDraw — log start/end,
• the static View.Draw —
• View.Draw
• Each phase of the draw flow

Tests

• TraceCategory_Draw_HasExpectedValue — enum value is 64
• TraceCategory_All_IncludesDraw — All flag includes Draw
• Configuration_Draw_CanBeEnabled — enabling the category doesn't throw

Note: Trace methods are [Conditional("DEBUG")] — tests must NOT assert on trace output (they'd fail in Release builds).

@copilot ensure UICatalog has a menuitem for this and the recently added Config flag as well (it was an oversights to not do that).

Done in 478c5f8. Added Con_figuration and _Draw CheckBox menu items to the UICatalog _Logging menu, following the same pattern as the existing Lifecycle/Command/Mouse/Keyboard entries. Both are enabled and toggle Trace.EnabledCategories via bitwise OR/AND.
