Update keepalive() to use new /api/{command} URL format

[MelvinBot]

The keepalive() method in Network.jsx always used addCommandToUrl() to construct the legacy /api/?&command=X URL format, even when the endpoint is configured for the new /api/{command} format (trailing slash). This updates keepalive() to check isNewURLFormat and build the URL path correctly, mirroring the logic already present in the post() method. The command is also removed from the parameters object so it isn't sent in the FormData body.

NAB - we don't need to keep the old-style format at this point. We could remove this whole else block and the if (isNewURLFormat)

@MelvinBot Do the above please.

Testing now...

Wait, that's the wrong thing to update. @MelvinBot we need to update the function addCommandToUrl instead. It should not use ${newUrl}&command=${command}, but instead of:

• Ensure that the passed url ends with /, or append /
• Return append the command after that, i.e. return something like ${url}/${command}

@MelvinBot Read the above and do the needful.

We also want to pass the CODE_REVISION as a new param called appVersion. We need to check if clients are using the newest revision. Do that too.
