* Fix race condition causing unhealthy repository message to be lost This commit fixes a race condition in the provisioning repository controller where the "Repository is unhealthy" message in the sync status could be lost due to status updates being based on stale repository objects. ## Problem The issue occurred in the `process` function when: 1. Repository object was fetched from cache with old status 2. `RefreshHealth` immediately patched the health status to "unhealthy" 3. `determineSyncStatusOps` used the stale object to check if unhealthy message was already set 4. A second patch operation based on stale data would overwrite the health status update ## Solution Introduced `RefreshHealthWithPatchOps` method that returns patch operations instead of immediately applying them. This allows batching all status updates (health + sync) into a single atomic patch operation, eliminating the race condition. ## Changes - Added `HealthCheckerInterface` for better testability - Added `RefreshHealthWithPatchOps` method to return patch ops without applying - Updated `process` function to batch health and sync status updates - Added comprehensive unit tests for the fix Fixes the issue where unhealthy repositories don't show the "Repository is unhealthy" message in their sync status. * Fix staticcheck lint error: remove unnecessary nil check for slice
