ref.listen(connectivityProvider, …) at start-time mounted the
StreamProvider immediately, which kicked off checkConnectivity()
with a 2s timeout. In tests that never reach the auth state
(smoke_test cold-launch path), that Timer leaked past widget tree
dispose and tripped the still-pending-timer assertion.
Drop the edge trigger — the 3s initial + 1min periodic + post-
enqueue nudge already cover the drain paths. Worst case on
reconnect is ~60s extra latency before the queue drains, which
is acceptable for an offline-resilience layer.
