Fix loading icon showing during automatic status checks

The loading icon was appearing during automatic background status checks
(every 10 seconds) even when users didn't click anything, which caused
confusion and made it seem like something was running unexpectedly.

Changes:
- Added manualCheckStatus() method to Application, Database, and Service
  Heading components that wraps the checkStatus() call
- Updated status component buttons to call manualCheckStatus() instead
  of checkStatus()
- Added wire:target="manualCheckStatus" to loading directives so the
  loading icon only appears when users explicitly click the refresh button
- Added delay.shortest to prevent flickering on fast operations

The automatic wire:poll.10000ms="checkStatus" now runs silently in the
background without showing the loading icon, while manual refreshes
still provide visual feedback to the user.
