Fixes #38117 - Refresh smart proxy sync history when proxy is updated

[sjha4]

What are the changes introduced in this pull request?

Refresh smart proxy sync history when sp is updated and only keep sync histories of repos available to capsule.

Considerations taken when implementing this change?

When LCE is removed from sp, we will now assume the sync history is not needed anymore.
What this does is that when env is added back, an optimized sync will not skip over this repo during sync.

What are the testing steps for this pull request?

1. Sync a LCE to the Smart proxy. This shows the package counts for cv correctly.
2. Now remove the LCE from Smart proxy.
3. Now add the previous LCE to the Smart proxy and sync it.
4. Package count now shows up as N/A
5. Refresh count doesnt fix this issue. Only complete sync fixes the counts again.

The issue here is that optimized sync simply skips the repos from the environment cause their old sync histories have not been cleared.

Working well! Just one comment about calculating the sync histories to delete.

Suggested change

	repos = smart_proxy_helper.repositories_available_to_capsule
	repo_ids = repos.map(&:id)
	if repo_ids.empty?
	self.smart_proxy_sync_histories.delete_all
	else
	self.smart_proxy_sync_histories.where("repository_id NOT IN (?)", repo_ids).delete_all
	end
	repos = smart_proxy_helper.repositories_available_to_capsule.select(:id)
	# Use size to ensure repos don't get loaded unnecessarily
	if repos.size == 0
	self.smart_proxy_sync_histories.delete_all
	else
	# Uses a single SQL query without needing to load IDs
	self.smart_proxy_sync_histories.where(id: repos).delete_all
	end

Ack..Updated to this with slight change to maintain previous logic:
self.smart_proxy_sync_histories.where.not(repository_id: repos).delete_all

Looks like tests broke, but the change on a running machine works well for me.

All relevant failures..Will update tests..
