Update `.htaccess ` for static files

Currently the `.htaccess` will going to redirect all the routes in the `index.php` belongs to route folder which will then process the route and will go directly to the static controller and then returns an encrypted routes, which changes the name of the static file on the network tab. Given that situation, it is really hard to maintain and locate files with those random names.

Open the repository `.htaccess` and inspect the rewrite rules that send all routes to `index.php`. Then inspect `index.php` and the static route/controller path mentioned in the report to confirm how static requests are being processed. Adjust `.htaccess` so static assets are excluded from front-controller rewrite, then run the app and request a known static file to confirm it is served with its original filename in the network response.
