What is new in DPIManager 1.1.0

- Complete UI Redesign (Feels native macOS): Two-pane layout with a floating display sidebar, translucent material, and edge-to-edge content replacing the old title bar. 
- Real Display Names: Shows actual marketing names like Samsung S27F350, LG FHD, etc instead of generic "Display 1440×900", with a MAIN badge for your primary display.
- Security Hardening & Bug Fixe: Removed a root-level shell injection vector, fixed the HiDPI disable bug, moved temp files to a private directory, and added input validation to prevent crashes.
