fix: webroot not working in archive view

[edsu]

Setting the base URL is required for the archived page to render properly when a --webroot is in use.

I tested the use of the webroot by running a local nginx configured to be a reverse proxy (see configuration below) and then running shiori:

go run main.go server --webroot shiori --port 8081

Prior to the fix my archived page looks like this:

And with the fix it looks like this:

I tested without --webroot and confirm that behavior still works.

nginx config

I tested on MacOS by installing nginx brew install nginx and then editing /opt/homebrew/etc/nginx/nginx.conf to look like:

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       8080;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm;
        }

        location /shiori/ {
          proxy_pass http://localhost:8081/;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

    include servers/*;
}

Fixes #1042

Thank you for taking care of this! I recall testing this out on my own when I moved the routes around, I need to add a service to the dev compose file to easily test this locally. Thanks!
