fix(ci): replace non-existent quote.wizard endpoint with leads.quote_request

The CRO homepage overhaul (f4f8a45) introduced url_for('quote.wizard')
in landing.html, but that endpoint never existed — the actual route is
leads.quote_request. This broke CI runs #99–#109.

Also adds landing_vs_col_us to i18n allowlist (brand name, same in both
languages).
