Summary:
Migrations were failing in snapshots due to the sandbox no longer
being started in snapshots. We now start up an instance of the
sandbox whenever there are migrations to run, and immediately shut
it down on completion.
Test Plan: Server test.

Summary:
Owners weren't able to access snapshots if access rules
that denied access to non-owners existed. The backend
was lowering snapshot document access to "viewers" as
part of implementing read-only behavior; this is now done
in the client, with document access for snapshots now
accurately reflecting the user's trunk access.
Additionally, sandboxes are no longer created for snapshots,
and background intervals aren't started for snapshots.
Test Plan: Browser test.
