Implements the secure single-admin panel entry (spec 7.6). - internal/store: modernc.org/sqlite (pure Go, static build), WAL + foreign keys, embedded PRAGMA user_version migrations; schema 0001 covers admin/settings/domains/applications/send_log/rate_limits (spec 9). - Setup secret-link (spec 7.6.1): 128-bit crypto/rand token, printed to log + /data/setup-token (0600), 10-min TTL with regeneration, per-IP rate limit, subtle.ConstantTimeCompare, failures don't invalidate, one-time admin form, permanent invalidation once admin exists (/setup 404). - bcrypt admin password; server-side username/password validation. - Login + in-memory sessions, crypto-random token, cookie HttpOnly/Secure/SameSite (Secure toggleable for dev HTTP), login rate limit, auth middleware. - html/template base layout + setup/login/dashboard, vendored htmx 2.0.4. - build/entrypoint.sh: fix bind-mounted /data ownership as root before supervisord drops to the unprivileged panel user (found via container test). Verified on selfpost.mixfed.ru: go vet/build/test/gofmt clean; e2e curl of setup+login flows; docker build + run with -v ./data:/data creates the DB and 0600 token owned by panel.
