Use contextual logging in leaderelection

Update leaderelection package to use contextual logging variants:
- Replace wait.JitterUntil with wait.JitterUntilWithContext
- Replace wait.Until with wait.UntilWithContext

This enables proper contextual logging support as part of the
structured logging migration.
