brand: rename product to "Read the Markets" (read.markets)

Browse source 
The product is now "Read the Markets" served at https://read.markets,
with the app at https://app.read.markets. "Cassandra" survives only as
the in-product AI persona (system prompt + "Ask Cassandra" chat label).

Centralised the brand in app/branding.py: BRAND_NAME, BRAND_SHORT,
DOMAIN, SITE_URL, APP_URL, EMAIL_FROM_DEFAULT. Jinja templates pull
{{ BRAND_NAME }} via globals registered in templates_env.py; Python
code reads branding.BRAND_NAME directly. The future-rename surface
is now a one-liner.

Updated: FastAPI app title, every page title (dashboard, news, log,
settings, upload, login, verify), header brand div, auth-card brands,
OTP email subject + HTML + plain-text bodies (incl. uppercase header
tag), OpenRouter X-Title + HTTP-Referer attribution headers, README.
Email tests now assert against branding.BRAND_NAME rather than the
literal string.

Internal identifiers deliberately kept on the legacy "cassandra" name
to avoid invalidating live sessions / advisory locks / configs:
cookies (cassandra_session, cassandra_pending) + itsdangerous salts,
MariaDB GET_LOCK keys, CASSANDRA_TOKEN env var, cassandra.css filename,
pyproject package name, localStorage prefs, outbound User-Agent strings.
