Fix notification message when Aphlict is not configured

Summary:
Before this change the footer in the notification bar was a bit
weird on the message "Notification server not enabled":

| Before | After |
|-----------|-----------|
| {F315024} | {F315001} |

Also a bit wrong on the "Connecting..." message:

| Before | After |
|-----------|-----------|
| {F315061} | {F315072} |

The fix involves a refactor in the HTML structure in order to
match the graphic rendered when Aphlict is configured…
