Drop the assistant's ⋯ menu; hiding is a right-click

Its two entries were "Thu nhỏ", which the − button immediately to its left
already does, and "Ẩn vào cạnh phải". A drop-list whose real content is one
action, half of it duplicating its neighbour, is chrome — removed at the user's
request.

Nothing became unreachable: collapsing is the − button and the dot itself,
hiding is a right-click on the dot (already there, and named in its tooltip) or
now on the open panel's header too.

This is a deliberate deviation from the audit page, which asks for "'Ẩn trợ lý'
dời vào menu ⋯". check_design_parity records it as that rather than quietly
scoring it done — the item is relabelled and its detail says where the action
went. check_help_dock stopped reading the menu's contents and now exercises the
routes: − collapses, the dot carries a context menu, hide reaches the edge.

24/24 checkers pass.
