Floating labels required the control to precede the `<label>` in the DOM so the floating animation could use a sibling (`~`) selector. That order made screen readers (e.g. NVDA) announce the label after the field's value instead of before it. Switch the SCSS to look forward with `:has()` so the `<label>` can come first in the DOM while the CSS still reacts to the control's state (focus, value, disabled, autofill). Reorder all examples, docs, and the visual test to label-first markup to match. Also give `.form-control-plaintext` its own copy of the control tokens so its `var(--control-*)` references resolve, fixing phantom borders and label misalignment. Fixes #41362

Summary
Fixes #41362.
Floating labels currently require the control to come before the
<label>in the DOM so the floating animation can use a sibling (~) selector. That ordering causes screen readers (e.g. NVDA) to announce the label after the field's value rather than before it — an accessibility concern flagged in #41362.This switches the SCSS to look forward with
:has()so the<label>can come first in the DOM (announced first by screen readers) while the CSS still reacts to the control's state (:focus,:not(:placeholder-shown),:disabled,:-webkit-autofill).:has()has been Baseline since late 2023, which is what makes this viable for v6.Changes
