- semantic HTML: step numbers inside h2, strong provider names, details
for adapter configs, strong error messages, fieldset drawer toggle hidden
- inline field errors via flash for no-JS controller fallback
- single form POST button for test email (works with and without JS)
- admin sidebar: remove brand/view-shop, move user email to footer nav
- replace inline style with .admin-setup-step-spaced class
- clean up unused CSS (.admin-brand, .admin-sidebar-header, etc.)

Render all adapter field sections in the form with CSS :has(:checked)
controlling visibility. Selecting a provider instantly shows its config
fields — no JS, no page reload, no server round-trip needed.
- Render all 6 adapter configs with data-adapter attribute
- CSS :has(:checked) show/hide rules per adapter in admin stylesheet
- Namespace field names per adapter (email[brevo][api_key] etc)
- Drop 4 transactional-only providers (Resend, Postmark, Mailgun, MailPace)
- Remove noscript "Switch provider" button and controller redirect workaround
- Remove configured_adapter hidden input tracking
- Hide JS-only test email button for no-JS users via noscript style
- LiveView progressively enhances with async save and test email

show all 10 providers in three groups (popular, transactional,
advanced) with category headings. fix phx-change clobbering text
fields, async test email sending state, integer parse crash on
bad port. add keyboard focus on card radios, fieldset legend,
WCAG-compliant badge contrast, responsive grid. extract shared
save_config into Mailer, add no-JS controller fallback with
configured_adapter hidden field for adapter change detection.
remove CardRadioScroll JS hook (no longer needed).
