fix(webhooks): handle GitHub repository renamed and transferred events

[drazisil-codecov]

GitHub repository webhook events for renamed and transferred actions were previously dropped with a warning log. Both are now handled by triggering a SyncRepos task using the GitHub App installation token (using_integration=True), which avoids any dependency on user OAuth tokens.

For transferred, the webhook payload contains the new owner — but the repo is still stored under the old owner in our DB. We bypass _get_repo and look up by service_id directly, then sync both the old owner (to reconcile their repo list) and the new owner (to pick up the repo). If the new owner isn't in Codecov yet, we log and move on.

Fixes CCMRG-40, CCMRG-725

Note

Medium Risk
Changes webhook side effects by initiating additional background sync tasks on rename/transfer events; risk is mainly around increased task volume or incorrect owner/repo lookups during transfers.

Overview
GitHub repository webhooks now handle renamed and transferred actions by triggering TaskService.refresh with using_integration=True to resync repository lists.

For transferred, the handler bypasses _get_repo and looks up the repo by service_id (since the payload owner is the new owner), then refreshes both the old owner and—if present in Codecov—the new owner (scoped via repos_affected when node_id is provided); missing repo/new owner cases are treated as no-ops with logging. Tests were added to cover rename/transfer sync behavior and edge cases (repo missing, new owner not in DB).
