feat: add App Config detail page with view/edit mode

Click a row in the admin App Config table to navigate to a dedicated
detail page at /admin/appconfig/:appId. Shows all config fields as
badges in view mode; pencil toggles to edit mode with dropdowns.

Traced processors are now editable (capture mode dropdown + remove
button per processor). Sections and header use card styling for
visual contrast. OidcConfigPage gets the same card treatment.

List page simplified to read-only badge overview with row click
navigation.
