v2.4.4: Rename Profiles to Configurations, add Identity Switcher

- Rename "Profiles" to "Configurations" in all UI text and 11 locale files
- Add identity switcher dropdown in header (green accent, fa-id-badge icon)
- Quick-switch player identity without opening Settings
- "Manage" action opens UUID Management modal
- Header tooltips explaining what each dropdown does
- Config dropdown icon changed from fa-user-circle to fa-sliders-h
- Global Escape key handler for closing modals and dropdowns
- Fix identity selector not clickable (missing -webkit-app-region: no-drag)
- Sync header identity name after all identity-changing operations
- XSS protection in identity list rendering
