fix(ci): E2E DinD networking + registry token auth

- playwright.config.ts: make baseURL configurable via PLAYWRIGHT_BASE_URL env var
- ci.yml: set PLAYWRIGHT_BASE_URL=http://host.docker.internal:8080 in e2e job step

Note: gitea.token registry auth not applicable — this repo uses GitHub Actions
with ghcr.io and secrets.GITHUB_TOKEN (already correct).
