* fix(tests): remove explicit beforeAll timeouts that override global hookTimeout
Integration tests passed 60s timeouts to beforeAll, overriding the
120s hookTimeout in vitest.smoke.config.ts. On CI the dev server
startup can consume the full 60s, leaving no time for setup + seeding.
Also bumps createTestServer's default waitForServer timeout from 60s
to 90s, leaving 30s margin within the 120s hook budget.
* fix(tests): don't remove shared node_modules symlink during cleanup
Multiple integration test suites run concurrently and share the
fixture/node_modules symlink. When the suite that created it finishes
first, its cleanup deletes the symlink, causing other suites to fail
with MODULE_NOT_FOUND when their server process tries to resolve astro.
The symlink is gitignored so it's safe to leave in place.
