fix(admin): ops page — add section description, remove redundant footer (#107)

Adds a one-line purpose description under the Ops heading so it is clear
what the section is for (shadow policy toggles, signal replay, per-user
actions). Removes the duplicate "User-level actions" subsection whose
content is now covered by the header description.
