Adds the management UI Daniel asked for end-of-session. Goes beyond
the original MVP scope (plan punted UI to v2) but the architecture
already supports it cleanly: stdlib http.server only, no new deps.
- furtka.api: minimal HTTP server. GET / serves a self-contained
HTML page (dark-mode card list, vanilla JS, no build step). GET
/api/apps + /api/bundled return JSON. POST /api/apps/{install,
remove} accept {"name": "..."} and call the same installer +
reconciler the CLI uses, so the placeholder-secret refusal and
per-app reconcile isolation flow through unchanged.
- furtka.cli: new `furtka serve` subcommand. Imports api lazily so
`furtka app list` / `reconcile` startup stays zero-cost.
- webinstaller: new furtka-api.service (Type=simple, restart on
failure, after reconcile). Caddyfile gets two new handle blocks
to reverse-proxy /api and /apps to localhost:7000. Landing page's
"App store coming soon" tile becomes a real "Manage installed apps
→" link to /apps.
- Bound to 127.0.0.1 by default; Caddy makes it LAN-reachable. The
UI shouts a "no auth, anyone on your LAN can install/remove" warning
at the top — Authentik integration is the proper fix later.
UX wrinkle worth noting: a placeholder-rejected install leaves the
app in /var/lib/furtka/apps/<name>/ (so the user can edit .env in
place). To re-trigger after editing, the Installed list now shows
both Reinstall and Remove buttons.
10 new tests: helper functions (list_installed, list_bundled with
hide-already-installed), install/remove endpoints with the no_docker
fixture, and two real-socket urllib smoke tests that boot the actual
HTTPServer on an ephemeral port and round-trip GET / + POST.
