release: 1.12.0 — rolls up 1.11.1 (reboot suppression hardening)

Bundled stable cut for prod. Contents since 1.11.0:

* fix(reboot): suppress webhook alerts during a fleet reboot
  regardless of cache driver. RebootAllAps now stamps a Setting
  (unifi.reboot_suppression_until) for 20 minutes at the start of a
  fleet reboot, and WebhookCheckService consults that Setting in
  checkDeviceTransition + checkReboot in addition to the existing
  per-MAC cache keys. Database-backed Setting always crosses
  container/process/cache-driver boundaries so the suppression can
  no longer be defeated by config differences.
