Rework Workspace ▸ Project to its wireframe

Section 4 draws a "Quản lý project" title with + Project mới on its right, a
caps PROJECT heading over the list, every row carrying "N đoạn chat · M task",
and the form reading Tên / Mô tả / Instructions / Thư mục làm việc. The screen
had none of that: the header still said "Workspace — Projects", the create
button sat at the foot of the list among the list's own controls, rows were
bare names, the folder field had no label, and Instructions carried a
parenthetical the drawing does not.

The row counts are the substantive part — they are the only thing on the screen
that says a project contains anything. Read once per refresh from
list_conversations() and list_tasks() grouped by project_id, not per row.

Delete stays under the list it acts on. The drawing does not show it, but it
does not show it moved either, and dropping a control is not something a layout
pass gets to do.

Also shortened by the drawing: "Đổi thư mục…"/"Mở thư mục" to "Đổi"/"Mở", which
the new "Thư mục làm việc" label above them now disambiguates.

check_project_screen covers the four points and fails when the count line is
removed.

22/22 checkers pass.
