diag(login): captureaza starea paginii la timeout pe input#user

Cand wait_for_selector('input#user') da timeout, logam URL, titlu, text
vizibil, lista de input-uri si salvam screenshot full_page - cat browser-ul
e inca viu. Necesar ca sa distingem intre WAF block, randare lenta si
selector schimbat, fara sa mai ghicim.

Handler-ul de blocare trackere inghite acum TargetClosedError la shutdown,
ca sa nu mai spameze log-ul cu "Future exception was never retrieved" si
sa ascunda eroarea reala.
