feat(detail): link genre and tag chips to the filtered catalogue

Genre chips now deep-link to /?genres=<id> and user-tag chips to
/?tags=<id>, reusing the homepage catalogue's existing filter params —
turning the detail page's metadata into one-tap discovery. Tag chips keep
their remove affordance (the Chip's href branch preventDefaults the remove
button). e2e asserts both chip hrefs.
