"Yes" status text (Code Signed, Signature Valid) in the "New MCP Connection" dialog has near-invisible contrast in Light theme

Steps to reproduce:

1. Create a new project
2. Trigger a "New MCP Connection" request (e.g. connect an external MCP client such as Claude to the Unity MCP Server)
3. Observe the resulting "New MCP Connection" tab, specifically the "Code Signed:" and "Signature Valid:" fields under "MCP Server Process" and "MCP Client Process"
4. Ensure Editor theme is set to Light (Preferences > General > Editor Theme)

Actual results: The "Yes" value for these fields is rendered in a bright/saturated green (measured ~RGB 117, 251, 76) against the light gray background (~RGB 200, 200, 200). Measured contrast ratio: 1.25:1.

Expected results: Text should meet WCAG AA minimum contrast requirements (4.5:1 for normal text, 3:1 for large/bold text). For comparison, the body text on the same panel (black on the same gray background) measures 11.9:1. 

Reproducible with versions: 2.18.0-pre.2(6000.7.0a5)

Tested on (OS): MacBook Pro - Tahoe 26.6.1
