Builds the Control Plane's browser UI (login, dashboard, Phase
registration, Development Credit entry/proposal/review, credential
admin, audit log) as a FastAPI + Jinja2 app over the already-finished
T03 backend, rather than from scratch — whynot-design's Lit web
components are vendored as static assets (source commit 4b62cffc,
v0.4.1), with lit itself resolved via an esm.sh CDN import map.
Session auth re-checks the credential token against the database on
every request rather than trusting the session cookie's cached rights,
so a mid-session revocation takes effect immediately.
9 new Docker-gated HTTP-level tests via FastAPI's TestClient (no
browser-automation tool available, so real rendering of the <wn-*>
components was never visually verified). All four WP-0009 tasks are
now done; workplan marked finished.
