Add CORS middleware and authentication middleware to the API server.

The `setupRouter` function in `main.go` now includes a CORS middleware and a token authentication middleware. The CORS middleware allows cross-origin resource sharing by setting the appropriate response headers. The token authentication middleware checks for the presence of an `Authorization` header with a valid bearer token. If the token is missing or invalid, an unauthorized response is returned.

In addition to these changes, a new test file `main_test.go` has been added to test the `/api/v1/auth` route. This test suite includes two test cases: one for successful authentication and one for failed authentication.

Update go.mod to include new dependencies.

The `go.mod` file has been modified to include two new dependencies: `github.com/spf13/viper` and `github.com/stretchr/testify`.

Ignore go.sum changes.

Ignore changes in the `go.sum` file, as they only include updates to existing dependencies.
