Codebase operator hangs during application onboarding: stuck in 'creating' status, cyclic branch update attempts, codebase unavailable (reproducible with clone strategy)

[zmotso]

During application onboarding through the codebase operator, the codebase may get stuck in the 'creating' status. In this state, the operator repeatedly attempts to update the branch every 5-10 seconds, but fails because the codebase remains in status 'unavailable'. No relevant logs are produced.

The issue is mostly reproducible when creating a new component using the clone strategy.
Workaround: Delete the codebase and repository, then onboard again.

Observed behavior:

• Codebase status remains 'creating' and does not proceed.
• Codebase operator attempts to update branch in a cycle (every ~5-10 seconds), but fails as codebase is unavailable.
• No logs indicating root cause are present.
• Most frequently occurs with the clone creation strategy.

Acceptance Criteria

• The issue with the codebase operator cyclically attempting to update branch during onboarding (up to codebase stuck in 'creating') is investigated and root cause analysis provided.
• Reproduction scenario using clone strategy and failing repo is documented.
• If possible, logs or traces relating to attempts (even absence of logs) are collected.
• Workaround (delete & re-onboard) is confirmed as at least a temporary solution.
