fix(web): prevent horizontal overflow at 768px on home dashboard (TEC-3089)

Add overflow-x-clip on the public layout and home page root wrappers,
plus min-w-0 / overflow-hidden guards on the ticker strip containers.
The ticker strip renders a whitespace-nowrap w-max flex row that can
push documentElement.scrollWidth past clientWidth at narrow viewports;
constraining its parent prevents the Playwright regression at 768p.
