Summary

Adds Serverless Workers as a new worker type alongside traditional workers, built on top of the worker-insights branch. All serverless data is mocked — no backend APIs exist yet.

• Workers tab: Unified table showing both traditional and serverless workers with a Type column distinguishing them. Reordered columns (Instance, Task Queue, Status, Type...). Three-dots context menus on serverless rows with View, Edit, and Delete actions.
• Configuration tab (new, third tab): Side-nav layout using VerticalNav. Placeholder items for General, Policies, Alerts (disabled). Serverless Workers section is functional with a list view, context menus, and a Create button.
• Create form: Single-page form (not a wizard) using superforms + zod. Fields for name, Lambda ARN, IAM Role ARN, region dropdown, and task queue. Advanced config (max workers, concurrency, rate, idle timeout) in a collapsible accordion with defaults. Async mock validation on blur for ARN format, IAM permissions, region mismatch, and task queue existence.
• Detail page: Two-column card layout showing connection config and advanced settings. Accessible from both the workers list and configuration list. Edit and Delete actions.
• Edit page: Read-only connection details (name, ARN, IAM role, region, task queue) with editable advanced configuration fields. Uses superforms + zod validation.
