Count a text field's characters against its maximum

Browse Source 
M3 lists "supporting text + character counter" as a configuration of both
text-field variants; nothing in the package drew one (plan step 24, audit
docs/audits/m3-alignment/inputs.md § Missing). `counter` on `<x-input>` and
`<x-textarea>` now puts `n/max` at the end of the supporting-text row, counted
from the control on every input, in the error colour past the maximum, and said
as M3's own "Character count, 5/20" from a polite region once typing settles.
