Auth Guard Features

• Automatically validates tokens from Authorization: Bearer <token> header
• Supports X-Auth-Provider: clerk header to specify Clerk tokens
• Injects workspace-id into query params based on:
  • Clerk: Uses orgId from token (or userId for personal workspace)
  • Firebase: Uses user's email
• Stores userId, workspaceId, authProvider in ClsService for easy access
• Bypasses authentication for routes marked with @Public() decorator
