fix(ui): tell Bitwarden to skip config and secret fields

The Input and Textarea primitives already opted config and secret fields
out of 1Password and LastPass autofill (data-1p-ignore / data-lpignore)
whenever autocomplete was off, but Bitwarden had no opt-out hint anywhere,
so it kept offering to fill and save API keys, tokens and integration
URLs. Emit data-bwignore alongside the existing hints, which covers every
field flowing through the primitives. Pin explicit autocomplete on the
change-password dialog so genuine credentials still autofill, and add the
ignore hints to the export passphrase and the few new-password admin
config fields that opt in directly.
