## Enforce submission lock on PUT /api/quotes

Modify the quote-creation handler to check the submissions lock before accepting a new quote. If locked, return `423 Locked` with a JSON error body.

Note: This ticket depends on ticket 35685a (GET /api/status) because that ticket adds `get_submissions_locked` to the `QuoteRepository` trait. Complete 35685a first.

---

## Files to modify

- `src/bin/api/handlers/mod.rs` — modify the `create_quote` handler (the handler for `PUT /api/quotes`) to add a lock pre-flight check

No new DB methods, routes, or types are needed.

---

## Change to create_quote handler

At the top of the handler body, before any other logic, add:

```rust
// Pre-flight: reject new submissions when locked.
match repo.get_submissions_locked().await {
    Ok(true) => {
        return (
            StatusCode::LOCKED,
            Json(json!({ "error": "submissions are closed" })),
        ).into_response();
    }
    Ok(false) => {}
    Err(_) => return StatusCode::INTERNAL_SERVER_ERROR.into_response(),
}
```

HTTP 423 is `StatusCode::LOCKED` in axum/hyper.

---

## Tests

- `PUT /api/quotes` while `submissions_locked = false` → `201` (existing behaviour unchanged)
- `PUT /api/quotes` while `submissions_locked = true` → `423` with body `{ "error": "submissions are closed" }`
- After unlocking (`submissions_locked = false`), `PUT /api/quotes` succeeds again → `201`

Use the in-memory/mock repo already used by other handler tests; expose a method to toggle the lock state on the test double.

## Validation

cargo fmt && cargo check && cargo clippy && cargo test
