feat: folder shares apply to hosts added later (#1343)

* feat: folder shares apply to hosts added later

Sharing a folder only fanned grants out to the hosts in it at the time.
The share is now also kept as a standing rule on the folder, and a host
created in or moved into it (or a subfolder) inherits the same access
and secret snapshots. Rules follow folder renames and can be stopped
from the share dialog.

* fix: stabilize folder access migrations
