fix(ui): port retail window control feedback

Browse source 
Map synthetic move and resize affordances to the exact DAT cursors, make chat top chrome movable, and replace stale primary-panel height caps with a dynamic screen-edge constraint. This keeps the retained wrapper adaptation aligned with retail Dragbar/Resizebar behavior.

@ -78,6 +78,36 @@ Magic are children of one `gmPanelUI`. The switch changes child visibility;
there is no child move and no per-panel top-level position. Dragging the parent
therefore moves the one position subsequently used by every child.
## Resize follow-up
The production end-of-retail LayoutDesc supplies the missing geometry oracle:
```text
LayoutDesc 0x2100006E
gmPanelUI host 0x100005FE 310 x 372
content parent 0x10000180 300 x 362, anchored on all edges
Inventory child 0x1000018B 300 x 362, anchored on all edges
Character child 0x1000018E 300 x 362, anchored on all edges
Magic child 0x10000190 300 x 362, anchored on all edges
top-center 0x1000065C Type 2 Dragbar, cursor 0x06006119
bottom-center 0x10000660 Type 9 Resizebar, cursor 0x06005E66
```
Every primary child therefore participates in the shared host's vertical
resize; Magic is not a fixed-height exception. Named
`gmPanelUI::ResizeTo @ 0x004BC6E0` delegates directly to
`UIElement::ResizeTo @ 0x00463C30`, whose only size limits are effective DAT
properties `0x3C..0x3F`. There is no retail 760-pixel Character limit and no
maximum captured from the host's original screen position.
acdream retains independent wrappers under IA-12, so the faithful adaptation
is to give each primary wrapper the same bottom-only vertical resize policy,
leave its maximum unbounded by an authored substitute, and calculate the
available desktop extent from its current position during the resize. The
viewport remains the physical limit; an old static maximum must not become a
smaller limit after the shared panel moves.
