Fix early provider resolution aborting commit/push and Option.none nullish coalescing fallback

- Wrap sourceControlProvider call in commit_push_pr action with Effect.catch
  fallback so provider resolution failure doesn't abort commit and push steps
- Replace ?? chain with Option.orElse for updatedAt in Azure DevOps PR
  normalization so Option.none() from closedDate falls through to creationDate
