Jonathan Hvid 09a10061b2 feat(admin): ResourceEditPanel + field renderers (no autosave)
Right-slide panel that renders a resource's edit form. Driven by the
URL: ?new=1 opens a fresh form, ?edit=<id> hydrates with the current
item. POSTs back to the same URL with _action (save | delete | <action
key>); the route handler in step 7 dispatches.

- FieldRenderer.astro: dispatches on field.kind, wraps each field with
  label + helper text + error state.
- fields/*.astro: one component per kind — Text, Textarea, Markdown
  (with Write/Preview toggle), Select, SelectAsync, MultiSelectAsync,
  MultiText (with add/remove), Date, Datetime, Number, Readonly.
- ResourceEditPanel.astro: header (title + close X), scrollable body,
  sticky footer (save + per-resource secondary actions + destructive
  delete when ops.delete is defined and item exists). Scrim closes on
  click, Esc, or the close link. Confirm-before-submit honours
  action.confirmText. Embedded sub-form sections render a placeholder
  until step 8 wires the pulse renderer.
- admin.css: panel chrome + scrim + slide-in keyframes, full field
  styling for every kind, mobile full-screen modal collapse.
- preview.astro: exercises every field kind so the panel can be
  eyeballed in a logged-in session. Try /admin/preview?new=1 and
  /admin/preview?edit=<id>.

Autosave deferred to Phase 2 per the approved deltas.
