WIP: Add configsync condition

[devguyio]

Warning

Very rough code that I didn't thoroughly review.

What this PR does / why we need it:

Adds a new HostedClusterConfigSynced condition to surface HCCO config sync errors to users.

When reconcileConfig fails, the error is now visible via a condition on HCP/HC instead of failing silently with infinite retries.

Which issue(s) this PR fixes:

Fixes

Special notes for your reviewer:

• Uses typed errors (ConfigSyncError, ConfigSyncErrors) to determine failure reason
• Condition reasons: InfrastructureSyncFailed, DNSSyncFailed, IngressSyncFailed, NetworkSyncFailed, MultipleConfigSyncFailed
• Condition added to expected e2e conditions with a version guardrail for clusters < 4.22

Checklist:

• Subject and description added to both, commit and PR.
• Relevant issues have been referenced.
• This change includes docs.
• This change includes unit tests.
