POST /r/<owner>/<name>/edit reads the current .pr-review.json via the
Gitea contents API (404 → start from {}), updates static_message and
model, then PUTs the file back as the bot identity. Static message is
stripped and capped at 400 chars; model is validated against
cost_model.PRICES (unknown → flash + redirect, no save). CSRF token is
the dashboard auth token (same value, simplest binding).
Helpers (_http) moved to urllib.request at module top so tests can patch
the entry point; the helper returns the Gitea status code so 404 (file
missing) cleanly omits sha on the create-PUT path.
6 tests under tests/pilot/test_dashboard_edit.py covering the happy
path, the 400-char cap, the unknown-model rejection, auth + CSRF gates,
and the file-missing creation path.
Mirrors webhook_server.py's BaseHTTPRequestHandler + ThreadingHTTPServer
shape. Pure stdlib, no pip deps. Routes:
GET / overview (totals + 7-day sparkline + top repos)
GET /r/<owner>/<name> repo summary (severity histogram + top findings)
GET /r/<owner>/<name>/<index> one PR's findings
GET /r/<owner>/<name>/<index>/raw raw Markdown body (via Gitea contents API)
GET /static/style.css dark-mode stylesheet
GET /login login form
POST /login compare token, set HttpOnly+SameSite cookie
POST /r/<owner>/<name>/edit (Tasks C+D)
Auth: when PRAGENT_DASHBOARD_TOKEN is set, every route except /login and
/static/* requires Cookie: pragent_dash=<token>. Unset → tailnet-only.
All HTML rendered via string.Template; every dynamic value is escaped
with html.escape(..., quote=True). No .format, no f-string templates.
12 tests under tests/pilot/test_dashboard.py.
