refactor(ui): remove duplicate OAuth tab from AddProviderDialog

- Remove AuthCenterPanel import and OAuth TabsContent
- Narrow activeTab type from three values to "app-specific" | "universal"
- Simplify footer by removing oauth branch, reducing to two-way conditional
- Change TabsList from grid-cols-3 to grid-cols-2
- OAuth authentication remains available in settings page and CopilotAuthSection
