fix(reboot): suppress webhook alerts during a fleet reboot, regardless of cache driver

Existing Cache::has('unifi:planned_reboot:{mac}') per-MAC suppression
relies on the cache driver being shared across the scheduler and the
snapshot-capture containers. In environments where the cache is
backed by something process-local (or where the keys expire before a
slow reboot completes), webhook alerts fire even though the dashboard
itself initiated the reboots.

RebootAllAps now also stamps a single Setting
(unifi.reboot_suppression_until) at the start of a fleet reboot,
covering a 20-minute window. WebhookCheckService checks this Setting
in addition to the per-MAC cache key, in checkDeviceTransition and
checkReboot. Setting is database-backed so it's always visible across
containers regardless of cache configuration.

v1.11.1.
