snapshots: change to snapshot list query

Admins can see all snapshots. Other roles can only see their own
snapshots.

Added permission check for deleting snapshots - admins can delete
any snapshot, other roles can delete their own snapshots or
snapshots that they have access to via dashboard permissions.
