chore: prefix all routes with account

[ebadi]

Description

No new functionality is added. Only all Flask routes have been updated to start with the /account prefix.
Example:

• /login -> /account/login
• /profile -> /account/profile

This change was made to simplify Nginx reverse proxy configuration and provide a single entry point for account-related endpoints. This also makes it possible for Nginx to serve static content (js, css, images) directly via nginx (instead of routing it through Flask), here is a sample nginx.conf

server {
        listen       80;
        server_name  localhost;

        location /account/ {
                proxy_pass http://app:5000/account/;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
        }
        location /static {
                root /var/www/front-end/; 
        }

}
