Bug: Inconsistent hostname/subdomain limitation in Routing

CodeIgniter version: 4.3.1

(1) `hostname` takes precedence over `subdomain`
if a route has both:
```php
$routes->get('/', 'Home::index');
$routes->get('/', 'Media::index', ['hostname' => 'media.example.com:8888', 'subdomain' => '*']);
```
`http://media.example.com:8888/ci431/public/` → `App\Controllers\Media::index`
`http://user.example.com:8888/ci431/public/` → `App\Controllers\Home::index`

(2) `subdomain` takes precedence over `hostname`
if two routes matches:
```php
$routes->get('/', 'Home::index');
$routes->get('/', 'Media::index', ['hostname' => 'media.example.com:8888']);
$routes->get('/', 'All::index', ['subdomain' => '*']);
```
`http://media.example.com:8888/ci431/public/` → `App\Controllers\All::index`
`http://user.example.com:8888/ci431/public/` → `App\Controllers\All::index`

Start in the Routing hostname and subdomain matching entry points; the issue provides reproduction routes and requests for media.example.com:8888 and user.example.com:8888. Reproduce both cases with CodeIgniter 4.3.1, then inspect the matching precedence. Done means hostname and subdomain constraints produce consistent, documented route selection in both examples.
