feat: add compare_geometry MCP tool to PepMcp

- Add LaserQuoteBaseUrl config property to PepTools
- Implement CompareGeometry() MCP tool to compare part geometry between PEP and LaserQuote
- Read LaserQuoteBaseUrl from appsettings.json in Program.cs
- Add appsettings.json with LaserQuoteBaseUrl config
- Update PepMcp.csproj to copy appsettings.json to output directory
