Update @appwrite/console (front end) to support TikTok OAuth integration:

• Add TikTok as a selectable authentication provider in UI
• Provide input fields for TikTok credentials in console's project settings/auth settings
• Display relevant error messages and validation for TikTok
• Update login/sign-in forms to include TikTok
• Write tests covering UI changes

Reference UI for other OAuth providers for consistency.
