Show a plain form field's errors under its name
Fields read their errors only under the wire:model name, so a Fortify
login form (name="email", no wire:model) never showed "These
credentials do not match". Without wire:model they now read the name,
turning brackets into dots.

{{-- One choice from a few, each with room for a line of explanation: M3's radio buttons.
A `<fieldset>` whose legend is the question, so a screen reader reads the group's name with each
option, and native radios sharing a name, so the arrow keys move between them. `options` as
`['id' => …, 'name' => …, 'hint' => …]` (`'disabled' => true` greys one out), `option-value`,
`option-label` and `option-hint` to read other keys, `inline` to lay them in a row from `sm`, and
`value` for the option chosen when the page loads (with `wire:model`, Livewire sets it).
Errors are read from the bag under the `wire:model` name
(resources/css/components/selection.css). --}}
