Reverse Proxy window is drawn incorrectly if Proxyman theme is set differently than system

[crankygeek]

Looks to be same issue as #1295

Proxyman version? (Ex. Proxyman 1.4.3)

Version 3.8.0 (30800)

macOS Version? (Ex. mac 10.14)

macOS 12.5

Steps to reproduce

1. Set Proxyman to Dark theme
2. Set macOS to Light theme
3. Click Tools > Reverse Proxy
4. Observe Reverse Proxy window theme

Screenshots (optional)
