ci(playwright): pre-pull images in parallel instead of on-demand

Each image was pulled on demand inside the first step that used it, serially
across steps — measured ~90s total on the runner (mariadb+phpfpm during
Composer install, node during Build assets, nginx+playwright during Run
playwright). Pull them all up front in one `docker compose pull`, which pulls
services concurrently, overlapping the smaller images under the large
playwright pull.

 - Sped up the Playwright CI job: it now runs in parallel (3 workers, sized to the 4-vCPU public
-  GitHub runner) instead of a single worker, added `ipc: host` to the `playwright` Compose
-  service so parallel Chromium does not exhaust Docker's default 64 MB `/dev/shm`, and dropped
-  the redundant `playwright install --with-deps` step (the pinned Playwright image already ships

 - Removed a dead statement in `MediaRepository::getPaginator()` that referenced the undefined
   variables `$page` and `$itemsPerPage`; the computed value was never used.
 - Fixed inverted user-type guard in `UserService::activateExternalUser()`: the "user is not of
