fix(infra): make MEILI_URL configurable; rename Discover → Catalogue in nav

- docker-compose.yml: MEILI_URL in x-infra-env was hardcoded to the local
  meilisearch container, ignoring the Doppler MEILI_URL secret entirely.
  Changed to "${MEILI_URL:-http://meilisearch:7700}" so prod reads from
  https://search.libnovel.cc while local dev keeps the container default.
- ui/+layout.svelte: rename nav + footer label from "Discover" to "Catalogue"
  (desktop nav, mobile menu, footer — all three occurrences).
