fix(login): inlocuieste networkidle cu domcontentloaded + wait selector

Pagina go.bancatransilvania.ro are tracking activ (Google Analytics,
LinkedIn, Facebook, omniconvert) care face request-uri continue 30+ sec
dupa load. wait_until='networkidle' nu se atinge niciodata si page.goto
face timeout dupa 30s.

Foloseste 'domcontentloaded' si asteapta explicit link-ul Login. Elimin
si fallback-ul mort cu networkidle din login() popup (15s wait inutil
dupa input#user — daca selectorul lipseste, networkidle nici el nu vine).
