Remove duplicate disable/enable logic and fetch() calls

readoutUnitChanged was manually setting disabled/aria-disabled/tabindex
attributes — duplicating Turbo.StreamElement.prototype.disableElement/
enableElement which already exists for this purpose. Replace with calls
to those methods.

Also replace fetch() in setDefaultUnit and drop with form.requestSubmit()
so Turbo handles CSRF, stream responses and lifecycle natively.
