Implement GET /shows Endpoint for Retrieving Broadcast Schedule

[Lapotor]

Description:

The task involves creating a Laravel API endpoint to retrieve the broadcast schedule for a specified time period. This endpoint will enable clients to request information about upcoming shows within a given date range. The API should be designed to accept query parameters such as start_date, end_date, and days to allow for flexible scheduling queries.

Tasks:

• Set up the Laravel route for the GET /shows endpoint.
• Create the necessary controller method to handle the request.
• Implement logic to retrieve the broadcast schedule based on the provided query parameters.
• Ensure that the response adheres to the specified JSON format.
• Implement error handling for cases where the request is invalid or the server encounters an error.
• Write appropriate unit tests to validate the functionality of the endpoint.

Additional Information:

• The endpoint should return a JSON array containing information about upcoming shows.
• Validate the input parameters to ensure they are in the correct format and within valid ranges.
• Pay attention to performance considerations, especially when querying the database for scheduling information.

Acceptance Criteria:

• The endpoint successfully returns a JSON array of upcoming shows.
• The endpoint handles invalid input gracefully and returns appropriate error responses.
• Unit tests provide adequate coverage and pass successfully.
