Settings: split Add/Added Models into 4 flat cards (no folds)

The previous 'Add Models' card had two collapsible folds (Local + API)
inside it and 'Added Models' had two inline subsections. Both folded
states added a click-to-expand step that wasn't earning its keep —
users coming to Settings to add a model don't want a fold, they want
the form.

Reshape: four flat admin-cards in the Services panel, each with its
own h2 title matching the rest of Settings:
  Add Local Model       (was Add Models → Local fold)
  Add API               (was Add Models → API fold)
  Added Local Models    (was Added Models → Local subsection)
  Added API Endpoints   (was Added Models → API subsection)

The collapsible JS hook in admin.js already guards on
'if (!head) return' so removing the .adm-section-toggle headers
turns it into a clean no-op — no breakage.

All input/list IDs preserved (adm-epLocalUrl, adm-epList-local,
adm-epList-api, etc.) so the rest of admin.js continues to work
unchanged. Probe / Clear-offline live on the Local card and act on
both lists together (existing behavior).
