When SyncCapsule runs multiple repos concurrently, two repos sharing the same Pulp3 distribution (same base_path/name) can race to create it. The losing task fails with:

Katello::Errors::Pulp3Error: {'name': [ErrorDetail(string='This field must be unique.', code='unique')], 'base_path': [ErrorDetail(string='This field must be unique.', code='unique')]}

The error surfaces only during async Pulp task polling (action: Actions::Pulp3::CapsuleContent::RefreshDistribution), so a service-level rescue cannot catch it.

Fix: move distribution refresh out of per-repo GenerateMetadata into a single RefreshAllDistributions action planned by SyncCapsule after all sync batches complete, and override rescue_external_task in RefreshDistribution to recover by retrying as a partial_update when a concurrent task wins the race.
