Show modeline icon immediately on chime-mode enable

Previously chime-modeline-string was nil until the first async check
completed (~10-15 seconds after startup). Now the icon appears
instantly with a "waiting for first event check" tooltip.

On validation or async failure, the icon stays visible and the
tooltip updates to show the error state instead of going blank.
