Review caught a behavior divergence: the generic UiMenu auto-set its own
Selected on any enabled pick, while the controller's EnabledProvider keeps the
null-payload specials (Squelch / Tell-to-Selected) enabled/white like retail.
So a special-item click set Selected=null and shifted the highlight onto the
deferred placeholders — and the menu tests masked it by using a different
(specials-disabled) gate than the controller ships.
Fix: clean MVC contract mirroring retail UIElement_Menu::NewSelection — the
widget REPORTS the pick via OnSelect; the controller OWNS Selected (it sets it
only for talk-channel payloads). A special-item click now fires OnSelect(null),
the controller ignores it, and the active channel + highlight stay put —
observably identical to the pre-generalization widget, and extensible for when
Squelch lands. Tests realigned to the controller's gate (specials white) and to
the controller-owns-Selected contract.

UiChannelMenu → UiMenu: removed ChatChannelKind, the 14-item array, the
button-text map, and the availability default. Generic surface: MenuItem
(label + object? Payload), Selected (object?), OnSelect, EnabledProvider,
ButtonLabelProvider, RowsPerColumn/RowHeight/ColumnWidth (all settable).
All draw/event mechanics unchanged — same popup geometry, same click
coordinates, same 8-piece bevel, same 3-slice button face.
ChatWindowController gains ChannelItems[], ChannelButtonLabel(), and
ChannelAvailable() (verbatim from old widget), and populates the
factory-built Type-6 UiMenu via find-by-id rather than constructing a
replacement widget. The Menu property type is now UiMenu. OnChannelChanged
wrap replaced with the generic OnSelect wrap for the ReflowInputRow hook.
DatWidgetFactory registers Type 6 → new UiMenu().
Tests: UiChannelMenuTests → UiMenuTests (10 tests, all green); factory
Type6 test added; ChatWindowControllerTests updated to use OnSelect.
Divergence register: AP-42 added (flat item model vs retail nested-submenu
MakePopup @0x46d310 — latent, unreachable through the chat menu).
