chore: rename e2e folder to catalogue + drop /inventory redirects

- tests/e2e/inventory → tests/e2e/catalogue (folder name only; playwright globs
  ./tests/e2e so nothing else changes).
- remove the next.config redirects from /inventory/{items,vendors}: the old
  routes are intentionally left free for a future feature.
