[codex] Fix failing tests and timeouts

[tkilias]

What changed

This PR collects the stability and robustness fixes needed to make the failing lifecycle checks reviewable on their own.

It includes:

• database deletion polling fixes and longer delete polling timeouts
• allowed IP lifecycle polling fixes and longer allowed IP polling timeouts
• debug logging around API helper responses used to diagnose flaky integration behavior
• hardened generated ApiError parsing so malformed backend error payloads do not crash error handling

Why it changed

The original branch mixed test-stability work, workflow changes, feature work, and refactoring. This PR isolates the behavioral fixes that address flaky deletion and allowed-IP polling, plus the API error hardening that supports those flows.

Impact

This should make the handwritten access helpers and their related tests more resilient to transitional backend states and malformed error responses.

Validation
