feat(privacy): reconnect the retroactive cleanup
The privacy filter only decides what gets written from now on. Whatever was stored before the user narrowed their channels stays there until something removes it, and that something has had no button since May. Two rules shape the section, both because this deletes history and cannot be undone: - Without a preview the apply button does not exist. Not greyed out, absent. A disabled button is something a user waits for; a missing one is something they have to go and earn. - A preview that no longer matches the settings counts as no preview. The old version only recoloured the number and left the button live, so a changed whitelist could be applied against counts computed for the previous one. The mapping from the live rule to CleanupRetainOnly is the part worth reading twice. CleanupRetainOnly takes one set and deletes everything else, so it can only stand in for the live rule where that rule narrows something: filter off means nothing is filtered, and an empty list means a full wipe, which has its own button and its own confirmation. Both cases now say so instead of offering a destructive action that does not mean what it looks like. Inside that, the allowlist is the whitelist itself plus any stored channel this build does not recognise while the unknown-channel failsafe is on. Deriving it from the counts instead would delete messages that arrive on a whitelisted but currently empty channel between the preview and the apply, and dropping the unrecognised ones would defeat the failsafe, which exists to hold on to a new patch's channel until the user has decided about it. The preview runs on a worker over its own connection. It is a GROUP BY across every stored row, the old version ran it inline on the draw thread, and holding the read lock for it would stall UpsertMessage on the framework thread for the length of the scan. Cleanup_Help_SavedNote stays unused: it tells the reader to press Save first, and the window it was written for had a Save button.
