## Problem The newly added flush task in https://github.com/neondatabase/neon/pull/9693 should hold timeline gate open, to avoid doing local IO after timeline shutdown completes. ## Solution Pass timeline gate guard to flush background task. The flush task do not need cancellation token b/c it will automatically shutdown when the front writer task drop the channel. - Refactor relevant paths to pass down `&Gate` instead of `GateGuard`.
