The `backup-archive` SSE collection (#10472) only announced a change when a client listed the repository: XO never read one on its own, so a subscriber learnt of a backup created, merged or deleted at the next listing by any client, and after a restart heard nothing from a repository until a client listed it. XO now reads the repositories itself: - every enabled repository is listed once XO has started, one after another, and a repository enabled later as soon as `updateRemote()` has stored it; - the changes this XO makes are pushed at once, for a repository whose journal can be replayed: at the end of each VM export to it (worker, no-worker mode and proxy alike), at the end of the job and after a deletion. A read in progress when `refresh()` is called reads again, since it may have missed the change, at most 3 times and never when that means listing the repository in full; - the other changes (the size the merge worker rewrites, another XO sharing the repository) are read by two timers, 2 repositories at a time and through the listing backoff: every minute from the journal, every 10 minutes by a full listing for a repository whose journal cannot be read, e.g. behind a proxy which does not expose it; - a repository is listed in full again an hour after its entry was built, rather than when it crosses a UTC day, which bounds the drift from what the journal does not record. The `fullListingInterval` parameter of its URL sets this delay, in whole minutes; the XO 6 and XO 5 repository forms now keep it when the repository is edited. The archives are registered through `registerCollection` like any other collection, which drops the REST API special case for them. Their events now carry an array of archives (`add`, `update`) or of ids (`remove`); SSE subscribers still receive one event per archive.
