Previously, LDK was very conservative and kept channel monitors around ~forever or until the user manually decided to prune them. Recently it introduced the `ChainMonitor::archive_fully_resolved_monitors` method, which we now call periodically: every time a wallet sync succeeds, we check whether the latest archival height is 6 blocks in the past and call `archive_fully_resolved_monitors`. As this is not permanently persisted, we will always try to archive any pruned monitors when the first background sync after fresh initialization succeeds, ensuring we call it regularly also on short-lived sessions, e.g, on mobile.
... which we previously omitted.

Fixes #300.

In the second and third commit, we fix previous omissions of
sync_wallets: we now update the timestamps read byNodeStatusand also have it update the fee rate cache.
