remember main window position

[OSXLich-Doug]

Summary

• save the main Warlock window X/Y/width/height per connected character
• restore saved bounds after the connected character is known
• keep the existing global width/height startup fallback

Tested

• ./gradlew :desktopApp:compileKotlin -PiosSkip=true -PlintSkip=true
• ./gradlew :core:ktlintCommonMainSourceSetCheck :desktopApp:ktlintMainSourceSetCheck -PiosSkip=true -PlintSkip=true
• manually verified two characters remember different main window positions

Note: no android environment available

Quick note - did not execute full ./gradlew tests. I don't keep an android environment installed here. So only focused testing occurred.
