Chrome's password manager matched the apikey-type account's Base URL + API Key
inputs as a login form and autofilled the last saved password by domain, so
editing a Gemini account could overwrite its apikey with a Claude key that
shared the same Base URL. Add autocomplete="new-password" plus data-*-ignore
attributes for 1Password / LastPass / Bitwarden to opt the field out of every
major password manager's autofill.
