Paul Fitzpatrick 134ae99e9a (core) add gvisor-based sandboxing to core
Summary:
This adds support for gvisor sandboxing in core. When Grist is run outside of a container, regular gvisor can be used (if on linux), and will run in rootless mode. When Grist is run inside a container, docker's default policy is insufficient for running gvisor, so a fork of gvisor is used that has less defence-in-depth but can run without privileges.

Sandboxing is automatically turned on in the Grist core container. It is not turned on automatically when built from source, since it is operating-system dependent.

This diff may break a complex method of testing Grist with gvisor on macs that I may have been the only person using. If anyone complains I'll find time on a mac to fix it :)

This diff includes a small "easter egg" to force document loads, primarily intended for developer use.

Test Plan: existing tests pass; checked that core and saas docker builds function
