fix(login): asteapta generos splash-ul SPA + reincarca popup la nevoie

Pe masina prod (Session 0, randare software) aplicatia Angular de la
goapp.bancatransilvania.ro ramane lenta pe splash-ul "Aplicatia ta de
banking business" si uneori depaseste 20s -> input#user nu apare.
Diagnostic confirmat: URL/titlu corecte, body gol, zero input-uri.

Asteptam load state, apoi input#user cu timeout 60s; daca tot nu apare,
reincarcam popup-ul o data si mai incercam. Worst case ~3 min, sub
timeout-ul de 2FA.
