fix(dialog): always show the toggles in the per-recipient permission modal

The modal passed through the panel's "custom preset selected" flag, so the
permission toggles were hidden whenever the recipient's permissions matched a
preset — and disappeared mid-edit as soon as the toggles happened to match one.
The modal is the custom-permission editor, so its toggles are always shown.
