{#
  Shared create + edit form for posts.

  Context:
    - user        : app.models.entities.User
    - post        : app.models.entities.Post | None   (None on create)
    - form        : dict {title, body_md, status}
    - errors      : dict {field_name: message}
    - csrf_token  : str

  Status dropdown policy:
    - On create: draft is default, admin may pick published.
    - On edit:  status is read-only here — use the toggle-publish
                button on the dashboard. Keeps the write path explicit.
