• Fixes Feature Request: Set a default "new site" location #587

How AI was used in this PR

• Copilot handled code changes for default site directory behavior, plus tests and linting based on repo rules.

Proposed Changes

• Resolve the default site directory dynamically (dialogs, copy site, proposed path, and site name generation) instead of using a constant because the path is now changed in run time
• Add user settings support for saving a default site directory and a picker UI.
• Update tests to cover the new behavior and mocks.

Testing Instructions

• npm test -- apps/studio/src/tests/ipc-handlers.test.ts
• npm run lint
• npm run make-pot

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?

Let me know if you need help with this change.
