test: fix Playwright Layer 2 tests - all 13 passingfeature/display-fix

- Fix SETUP_HTML innerHTML newline syntax error (single-quoted string can't span lines)
- Fix route interception: use page.goto with http://tollgate.test/setup instead of page.setContent
- Add **/setup route for serving mock HTML
- Fix Layer 1 POST tests: handle ECONNRESET gracefully, accept any error message
- Add Layer 1.5 redirect test (needs live board)
- Add **/setup route to rescan test
- Load page with waitUntil: networkidle
