feat(ui): Campaign OP slice OP2 — tab control, template ListBox, UIOption widget mappings

Ships the two new widget primitives the retail Options panel needs plus the
four remaining UIOption_* factory mappings, so every tab page (OP3-OP6) has
somewhere to mount.

- ElementReader/ElementInfo gain three new dat-property readers, following
  the existing effective-state-resolution pattern (never a per-state
  first-wins scan, per the round-5 N1 lesson): the Type-8 tab table
  (property 0x2E -> TabTable), a ListBox's row-template list (property
  0x64 -> TemplateList), and scrollbar linkage (property 0x72 ->
  ScrollbarElementId). LayoutImporter gains one hook
  (IUiChildrenAttachedListener) so a widget can resolve cross-references
  its own dat properties name by id once its subtree actually exists.

- UiTabControl (Type 8): switches exactly one page-slot child visible,
  syncs each tab button's Open/Closed state via the existing
  RetailTabBinding helper, and honors the authored default tab on mount.

- UiTemplateListBox (Type 5 with an authored template list): wraps a
  UiScrollablePanel viewport (sealed, so composition not inheritance) and
  ports AddItemFromTemplateList(index) — the resolver seam a page
  controller wires with real DAT access via the SAME
  LayoutImporter.ImportInfos(dats, layoutId, elementId) overload
  RetailDialogFactory already uses for its catalog LayoutDesc.

- DatWidgetFactory maps the four remaining UIOption_* widgets, each
  verified against the regenerated options_2100002B.json fixture before
  writing any code: 0x10000037 (Slider) is structurally an ordinary
  horizontal UIElement_Scrollbar, so it reuses BuildScrollbar directly;
  0x10000038 (Menu) is structurally identical to the vendor category
  dropdown UiMenu already models, so it reuses `new UiMenu()` like the
  Type-6 case; 0x10000036 (CheckboxSlider) composes an existing
  UIOption_Checkbox child + UIOption_Slider child via the new
  UiOptionToggleSlider wrapper; 0x10000044 (CheckboxBitfield64) authors
  zero children in the dat (every row is added at runtime via retail's own
  AddChild(lowMask, highMask, label, tooltip) call shape), so it's a new
  UiCheckboxBitfield64 composing UiButton per row. No new drawing code
  anywhere in this set.

- Five new committed fixtures (options_2100002B/2100002A/21000028/
  2100005C/21000029) plus 25 new conformance tests pinning the tab table
  (4 entries, Gameplay default), all three template arrays, scrollbar
  linkage, every new widget-type mapping, and a UiTabControl behavioral
  test (switch -> exactly one page visible, click-through the tab
  button). The Character ListBox's authored 6-header/49-toggle shape
  (lane B section counts) is proven reachable end-to-end through
  AddItemFromTemplateList against the committed fixture.

- Regenerating fixtures also touched 27 PRE-EXISTING, unrelated fixtures
  (an Outline/OutlineColor field pair added by an earlier commit,
  bcc34ee3, that predates when those fixtures were last regenerated).
  Per the slice contract, that drift was NOT committed — reverted back to
  HEAD, only the five new Options-panel fixtures are new files here.

- Filed TS-72: UiCheckboxBitfield64's click-toggle bit math (AND/OR
  set/clear semantics) is a documented approximation — the decompiled
  excerpt this campaign pulled covers UIOption_CheckboxBitfield64::Apply's
  WRITE side, not its own click-handler's bit math. Flagged for OP5 (the
  Chat tab controller, the first consumer that reaches the wire) to
  verify against the real decomp before any live transaction depends on
  it; nothing user-reachable can observe this yet.

Full Release suite: 12,770 passed / 4 skipped / 0 failed (was 12,745/4/0
post-OP1 — 25 net new tests, zero regressions).
