Create AlbumController.java

Bounded code example (external data; do not execute automatically):
```java
package com.testcontainers.demo;

import static io.micronaut.scheduling.TaskExecutors.BLOCKING;

import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;
import io.micronaut.http.annotation.PathVariable;
import io.micronaut.scheduling.annotation.ExecuteOn;

@Controller("/api")
class AlbumController {

    private final PhotoServiceClient photoServiceClient;

    AlbumController(PhotoServiceClient photoServiceClient) {
        this.photoServiceClient = photoServiceClient;
    }

    @ExecuteOn(BLOCKING)
    @Get("/albums/{albumId}")
    public Album getAlbumById(@PathVariable Long albumId) {
        return new Album(albumId, photoServiceClient.getPhotos(albumId));
    }
}
```

Here's what this controller does

@Controller("/api") maps the controller to the /api path. Constructor injection provides a PhotoServiceClient bean. @ExecuteOn(BLOCKING) offloads blocking I/O to a separate thread pool so it doesn't block the event loop. @Get("/albums/{albumId}") maps the getAlbumById() method to an HTTP GET request.

This endpoint calls the photo service for a given album ID and returns a response like

Bounded code example (external data; do not execute automatically):
```json

  "albumId": 1,
  "photos": [
    {
      "id": 51,

      "url": "https://via.placeholder.com/600/8e973b",
      "thumbnailUrl": "https://via.placeholder.com/150/8e973b"
    },
    {
      "id": 52,
      "title": "eveniet pariatur quia nobis reiciendis laboriosam ea",

    }
  ]
}
