Add Search API Endpoint for Logo Retrieval

What is this issue related to?

Feature

Description

This feature aims to implement the Basic Logo Search API, which fetches a list of logo URLs starting with specified characters. This functionality will allow users to display logos that share a common theme based on their initial characters.

Endpoint: /api/business/search?key={KEY}&API_KEY={YOUR_API_KEY}

Method: GET

Parameter	Type	Description	Required
key	string	The initial character(s) that the logo URLs should begin with.	Yes
API_KEY	string	The API Key generated from the dashboard.	Yes

The tests for the same should be implemented as well to ensure correctness.

Expected Behavior

The API should return a JSON response containing a list of logo URLs that start with the specified key parameter.
If the key is missing or empty, the API should respond with an appropriate error message indicating that the parameter is required.
If the API_KEY is invalid or missing, the API should return an authentication error message.

Current Behavior

No such API exists now.

Additional Information (optional)

No response
