Fix TTD Memory Query widget scroll bar clipping issue

[Copilot]

Problem

When there are many results in the TTD Memory Query widget, the scroll bar doesn't work properly, and the last few results can only be seen when closing the bottom sidebars. This makes it difficult to view and interact with all query results, particularly when working with large TTD memory traces.

Root Cause

The issue was caused by fixed minimum size constraints on the widgets:

• TTDMemoryQueryWidget had setMinimumSize(800, 600)
• TTDMemoryWidget had setMinimumSize(900, 700)

These hard-coded minimum sizes prevented the widgets from properly adapting to the available space when placed in a sidebar. When the sidebar was constrained vertically (e.g., by bottom sidebars being open), the fixed minimum sizes caused the table widget to extend beyond the visible area. Since the parent widgets couldn't shrink below their minimum sizes, Qt's layout system was unable to properly allocate space, resulting in the table being clipped and the scroll bar becoming non-functional.

Solution

Replaced the fixed minimum size constraints with proper Qt size policies:

1. Set QSizePolicy::Expanding on both TTDMemoryQueryWidget and TTDMemoryWidget to allow them to adapt to available sidebar space
2. Set QSizePolicy::Expanding on the results table (m_resultsTable) to ensure it properly expands and contracts within the layout

This follows Qt best practices for widgets in dynamic layouts, allowing the layout system to properly manage widget sizes based on available space while ensuring the scroll bar functions correctly.

Impact

• ✅ Scroll bar now works correctly regardless of the number of results
• ✅ Users can view all results without closing bottom sidebars
• ✅ Widgets properly adapt to different sidebar configurations
• ✅ No functional changes - only layout behavior improvements
