Stage 7: ui-test CI — Playwright browser/e2e best-effort

The Gitea runner is an act host executor without apt privileges, so
'playwright install --with-deps chromium' (apt-get) hung ~51m then failed. Drop
--with-deps, bound the browser-install + e2e steps with timeouts and mark them
continue-on-error so a runner lacking GUI libs can't block the gate. The strict
gate stays check/unit/build/size; the e2e smoke remains a hard local pre-push check.
