feat: CSP + security headers middleware + session-fixation defense (1.0.0-27)
#6 — defense-in-depth security headers:
* New _SecurityHeadersMiddleware emits five headers on every response:
  - Content-Security-Policy: tight default-src 'self', allow-list the
    three CDNs we actively load (unpkg for HTMX, cdnjs for QR codes,
    jsdelivr for xterm.js), plus 'unsafe-inline' for the inline script
    in settings.html and inline style in job_print.html. Tighten via
    nonces later if you want true CSP-level XSS protection.
  - X-Content-Type-Options: nosniff
  - Referrer-Policy: same-origin
  - X-Frame-Options: DENY (no clickjacking)
  - Permissions-Policy: camera/microphone/geolocation/interest-cohort
    all blocked
* Middleware ordering: SecurityHeaders -> AuthGate -> Session, so
  headers go on EVERY response including 401/403/redirects.

#7 — session-fixation defense:
* request.session.clear() now runs BEFORE setting user_id/username on
  successful /login AND /api/v1/auth/setup. Discards any pre-login
  payload an attacker might have seeded the cookie with. Combined
  with SameSite=strict + the HMAC-signed Starlette session cookie,
  this closes the residual fixation surface.

Verified: curl -sSI /login returns all five headers; container boots
clean; /health 200; existing session for the operator continues to
work because we only clear on the LOGIN flow itself.
