Viktor Barzin 411524a10d kured: drop Mon-Fri restriction, reboot any day 
The weekday-only schedule was a 2026-03-16-incident-era guardrail when
the rest of the safety net was thin. Today's gates — halt-on-alert,
sentinel-gate Check 4 (24h soak via node Ready transitions), the
K8sUpgradeStalled alert, drainTimeout=30m, concurrency=1, and the
sentinel-path fix from earlier today — make weekend reboots safe and
just clear the backlog faster.

Effect: 5 pending node reboots clear in 5 calendar days instead of
queueing up over weekends. The K8s version-upgrade detection at Sun
12:00 UTC self-defers if a Sunday-morning kured reboot fires (the
RecentNodeReboot alert is in the Upgrade Gates ignore-less list for
the version-upgrade preflight — same mechanism kured uses).
