Daniel Salazar d8ebfc8023 feat: delivery re-check cache, revocation and anchor settle (PUT-1677) (#3681)
* feat: delivery re-check cache, revocation and anchor settle (PUT-1677)

* fix: authorize re-anchors, settle each row once, purge revoked backlog (PUT-1677)

- A path-form row whose anchor is deleted only climbs to an ancestor its
  holder may still watch under the mode it subscribed with; otherwise it ends
  with `anchor_deleted`. It used to land on any surviving ancestor (a guest's
  row on the owner's home), where the re-check denied every delivery but the
  row still held an anchor slot and a filter evaluation there.
- After a climb the new anchor is re-verified and the climb repeated if a
  recursive delete took that level too, instead of leaving the row on a dead uid.
- suspend() is one conditional write per row and reports which rows it was the
  one to suspend; concurrent settles of the same grant (an unshare revokes
  several strings) no longer each purge, forget and notify the same rows.
- One "subscriptions ended" notification per holder and app, carrying the count
  and subjects, instead of one per row.
- A revoke that removed nothing no longer announces; the sweeper purges (not
  defers) the backlog of a permission_revoked row; the reap purges pending
  entries with the row.
- The delivery auth cache indexes entries by subscription so forget() is not a
  scan of the whole cache.
