Consider helpful index page messaging

[rudokemper]

It's happened several times that users navigate to the CoMapeo Archive Server URL in the browser, and encounter the "Hello" messaging on src/static/index.html, and were left confused.

This has happened in particular for Guardian Connector users who have seen a web map of their CoMapeo data, but can't remember the URL, and reasonably might expect it is the same as the Archive Server URL. (Even moreso because their Archive Server is hosted on Guardian Connector, and therefore has a URL like https://comapeo.<alias>.guardianconnector.net)

Perhaps instead of "Hello from CoMapeo!" in three languages, this page could offer a clarification? Something like:

Welcome to the CoMapeo Archive Server. At the moment, this URL is only meant to be used as an Archive Server peer in a CoMapeo project.

That said, I can imagine two objections:

1. You don't want bad actors who stumble on the page to actually know they can do this, and abuse the server. (Since there is no mechanism in place to prevent anyone from adding a given remote archive server to their project.)
2. Awana might have plans to actually serve something useful from this index page in the future.

Thought to file the request all the same, for your consideration and information that the status quo is confusing some users.
