calendar and contacts are core again, with radicale as a plain sidecar

Reverses the 2026-08-13 decision to make caldav an app-store entry. Three
reasons it does not belong there.

It is not an integration. Photos-via-Immich or torrents-via-Transmission assume
you already run the thing; a calendar assumes nothing, and a personal server
without one is missing a baseline rather than an optional app.

It needs TWO top-level routes, /calendar and /contacts, and a plugin gets one —
derived from its appName, which is what makes it structurally impossible for a
plugin to shadow a core route. Nobody thinks "I'll open my dav", so collapsing
them under /dav was the wrong trade, and weakening the namespace guarantee to
allow two was a worse one. As core routes the question does not arise.

And it never actually needed Docker. Radicale is a ~2MB Python package;
sidecar/caldav/radicale.ts already spawns it directly on loopback with
http_x_remote_user. The container came from the app store making everything a
container, not from anything Radicale requires.

So: the routers are mounted again (/caldav for the UI's JSON door, /dav for app
passwords, the top-level /dav sync door and the two .well-known redirects),
officer-caldav joins CORE_PROCESSES, radicale joins the machine-setup package
list for all four package managers, and the catalogue entry is gone.

members.test.ts re-anchored a fifth time — caldav was one of two `accounts`
services and memos is now the last. Noted in the test that the sixth time
should be a literal fixture instead.

Verified: assertPermissionTotality accepts /caldav and /dav, tsgo clean,
1085 pass. NOT yet verified against a real client — radicale is not installed
on this machine.
