test(e2e): dismiss iOS save-password prompt + diagnostic screenshots

iOS's system 'Save Password' / iCloud Keychain prompt overlays the home
screen after sign-in. The flow already dismisses Android's Google
Password Manager equivalent; mirror that for the iOS variants
("Save Password", "Strong Password", "AutoFill Passwords") by tapping
the dismissal button ("Not Now", "Never for This Website", "Don't Save").

Also adds two screenshots so the next failure isn't blind:
- debug-04-after-password-continue at the end of sign-in
- debug-assert-signed-in-state at the start of assert-signed-in
