Merge branch 'refactor/groups-phase1'

Groups refactor, phases 1-3.

The root model replaces the old `upload` flag and group-wide `member_upload`
with per-root `writable`/`removable`/`ejected`, carried by a `RootSet` that
both front doors — the loopback API and signed MNP — reach through the same
`ops` functions. MNP goes to 1.1, additively: the roots table now rides on
`index_delta`, so a root added, removed, ejected or plugged reaches every
connected client instead of only whoever reloaded.

The group UI becomes a plugin architecture: an application is a registry
entry in `apps.js` plus its own files, with directories stored generically
by `ops.set_app_directories` under whatever the app is called. A reference
application, hidden behind `?dev=1`, is what makes that claim testable —
adding it is what found the two places still naming apps by hand.
