public: landing + pricing + legal pages, apex-ready, lawyer-reviewed

Adds the unauthenticated surface that's needed to invite outsiders:

  - Landing (/) — dual-purpose root: dashboard for logged-in users,
    landing for everyone else. New maybe_current_user soft-auth helper
    in app/auth.py supports it without disturbing the per-route
    require_token deps on /news, /log, /upload, /settings.
  - About, Pricing, Disclaimer, Terms, Privacy — own router
    (app/routers/public.py), no auth dep, shared public_base layout
    (brand link, thin nav, footer with legal links + ICO ref + date).
  - Editorial positioning: news aggregator with a macro brain; tagline
    "Understand markets. Don't gamble on them."; anti-trading-as-gambling
    stance carried through About and Landing.

Legal pass following an independent lawyer-style review:

  - Privacy: explicit UK-GDPR Art. 6 lawful-basis section; Art. 22
    automated-decision line; explicit consent for sessionStorage sync
    key (PECR); 30-day IP-log retention; Art. 21 objection right;
    Children clause; Art. 33/34 breach-notification clause;
    international-transfer mechanism (IDTA + UK Addendum). ICO
    registration ZC098928 surfaced at the top.
  - Pricing: paid-card AI-portfolio-analysis bullet rewritten to remove
    advice-shaped wording ("what would invalidate the posture" gone);
    added italic carve-out citing FSMA / FCA COBS.
  - Disclaimer: separate EU/EEA carve-out + MAR 596/2014 Art. 3(1)(34)
    commentator safe-harbour; "qualifies the Terms" line; hallucination
    wording fixed.
  - Terms: cl.4 explicit AI-training prohibition + harassment line;
    cl.5 CCR 2013 14-day cancellation; cl.7 softened AI copyright
    claim under CDPA s.9(3) ambiguity; cl.8 proportionate suspension +
    pro-rata refund for paid users; cl.10 CRA 2015 Pt 1 statutory-rights
    carve-out from the liability cap; cl.11 right to close account on
    material change; cl.12 non-exclusive jurisdiction + UK consumer
    local courts.

Code-side enforcement of the Privacy claim:

  - openrouter.py: outbound OpenRouter calls now carry
    X-OR-Allow-Training: false. DeepSeek doesn't expose a per-request
    flag; the Privacy page discloses this caveat verbatim.

Apex domain prep:

  - branding.APP_URL flipped to https://read.markets (was app.). DNS for
    the apex already resolves; pending operator NPM step is a cert that
    covers the bare apex + a 301 from app.read.markets. No hard-coded
    subdomain references remain in code (verified with grep).

Nav + chrome:

  - app dropdown gains Pricing / Terms / Privacy / Disclaimer links.
  - login.html gains a small legal-links footer for the
    highest-leverage moment to surface them.
