chore(auto-upgrade): run cronjob hourly at :23

[saadqbal]

Summary

• Switches default autoUpgrade.schedule from "23 2 * * *" (daily 02:23 UTC) to "23 * * * *" (hourly at :23) so deployed clients converge on the latest chart within ~1h instead of ~24h.
• Companion PR will cherry-pick this single commit onto a branch off main so prod gets only this change without pulling unshipped develop commits along with it.

Closes #111 (dev side — the prod-side PR will reference the same ticket).

Test plan

• helm template ... | grep -A1 schedule: shows 23 * * * * on a fresh render
• client/tests/auto_upgrade_test.yaml still passes (helm unittest client/)
• After deploy, kubectl get cronjob -n <ns> -l app.kubernetes.io/component=auto-upgrade shows the hourly schedule

Note

Low Risk
Low risk: only changes the default CronJob schedule and its unit test expectation, with no changes to the upgrade logic itself. The main impact is increased upgrade/check frequency (more cluster activity and repo polling).

Overview
Switches the default autoUpgrade.schedule from daily "23 2 * * *" to hourly "23 * * * *", so the self-upgrade CronJob checks/applies chart updates up to once per hour.

Updates the Helm unittest (client/tests/auto_upgrade_test.yaml) to assert the new default schedule.
