Restyle the contact-change form with house CIBG surfaces instead of hand-rolled markup: the read-only BRP address now uses app-data-block/app-data-row (grey datablock), and the phone field sits in a plain <fieldset> inside the existing .form-horizontal form (inherits the CIBG grey box). No new CSS surfaces; row keys reuse the address.* i18n ids. Logic/machine/specs unchanged. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
