fix: AI profile display issues for Codex models

- Fix Codex profiles showing as 'Claude Sonnet' in UI
- Add proper Codex model display in profile cards and selectors
- Add useEffect to sync profile form data when editing profiles
- Update provider badges to show 'Codex' with OpenAI icon
- Enhance profile selection validation across feature dialogs
- Add getCodexModelLabel support to display functions

The issue was that profile display functions only handled Claude and Cursor
providers, causing Codex profiles to fallback to 'sonnet' display.
