fix(e2e): wait for leader election & measure timing for better monitoring

TestClusterExtensionAfterOLMUpgrade was failing due to increased leader
election timeouts, causing reconciliation checks to run before leadership
was acquired.

This fix ensures the test explicitly waits for leader election logs
(`"successfully acquired lease"`) before verifying reconciliation.

Additionally, the test now measures and logs the leader election duration
to help monitor election timing.
