refactor(operator): drop redundant profile card from sidebar foot

The .me-wrap block in OpSidebar was an inert button — no click handler,
no menu — and duplicated the avatar already shown in the topbar. Remove
it so there's a single place to render the user (topbar), making room
for the avatar dropdown that's landing next.
