fix(ui): firmware state syncs across screens immediately (v0.16.7-beta)

Firmware actions on the device Config tab (check/install RouterOS,
check/install RouterBOOT) and Firmware-page actions now invalidate the
shared react-query caches on success — devices list, device header,
firmware overview, dashboard "Things to handle", and Security Center
findings. Previously they only updated local component state, so other
screens showed stale "update available" data for up to 30s until their
own background refetch fired, even though the backend had already
persisted the new state.

Browser-verified: after a firmware check on the Config tab, /api/devices
refetches within the same second (sidebar observer) and the Devices page
fetches fresh data on mount; both screens agree immediately.
