Eric Traut c3eeaae9a3 Gate new app-server work during graceful shutdown (#43959) ...

## Why

New client requests and automatic continuations can start more work while the app-server is draining. Shutdown also needs to account for requests still preparing or submitting work before they appear as running turns.

## What changed

- Close a shared admission gate when shutdown begins, rejecting new turn work and thread lifecycle changes with the server-draining error.
- Apply the gate to automatic turn starts, including queued work and goal continuations, and recheck serialized turn requests before execution.
- Wait for admitted requests and running turns to finish, while preserving forced shutdown. Keep reads and `turn/interrupt` available during drain.

## Testing

Add coverage for admission permit tracking, discarded queued requests, forced shutdown, and WebSocket drain behavior, including request rejection, interruption, and suppression of automatic continuations.
