fix: vendor-based Docker build, playwright upgrade, and CI cross-repo checkout

- Dockerfile now installs schwab-scraper from vendor/ dir (no git needed)
- Upgrade playwright to latest to match browserless chromium container
- CI workflow checks out schwab-scraper into vendor/ before build
- Add scripts/build.sh for local builds via docker-test
- Add curl to runtime image for compose healthcheck
- Increase memory limit to 512M for large account position scraping
