Discord(et al.) embedded URLs (#2740)

## Description:

Changes URL embeds within other platforms, e.g. Discord, WhatsApp & X.

Updates game URLs to `/game/<code>` instead of `/#join=<code>` (required
for embedded URLs). An added benefit of this is that you would be able
to change a url from `openfront.io/game/RQDUy8nP?replay` to
`api.openfront.io/game/RQDUy8nP?replay` (add api. In front) and be in
the right place for the API data.

Updates URLs when joining/leaving private lobbies

Appends a random string to the end of the URL when inside a private
lobby and options change - this is to force discord to update the
embedded details.

Updates URL in different game states to ?lobby / ?live and ?replay.
These do nothing other than being used as a _cache-busting_ solution.
