Compare performance: Show names of query runs being compared

[asgerf]

Adds a list of the query runs being compared, and their relative order. The UI for opening the comparison doesn't make it clear which is run will appear on the left or on the right.

Pull Request Overview

This PR enhances the performance comparison UI by displaying the names of query runs being compared and clarifying their relative positions (left vs right). The implementation refactors the data flow to pass complete query info objects instead of just log paths, enabling the extraction of query names for display.

• Refactored showResults to accept CompletedLocalQueryInfo objects instead of file paths
• Added query run names to the comparison UI with a list showing which runs are being compared
• Updated the message interface to include both name and data for each query run
