fix(paperdoll): port quest-gated Aetheria slots

Add the three authored blue, yellow, and red sigil backgrounds and drive their visibility from player PropertyInt.AetheriaBitfield bits 1/2/4 at login and on live updates, matching gmPaperDollUI::UpdateAetheria. Include the sigil equip masks in the shared slot table and narrow AP-108.

 | AP-105 | **PARTIAL 2026-07-10 (Wave 2.2)** — inherited scrollbar media/roles now come from DAT (decrement/top `0x06004C69`, increment/bottom `0x06004C6C`). Retained chat still lacks complete tab/filter/unread, social availability, squelch, and focus-opacity behavior; a second ChatVM still loses FPS/position providers. | `src/AcDream.App/UI/Layout/DatWidgetFactory.cs`; `ChatWindowController.cs`; chat mount in `GameWindow.cs` | Shared log/send path, wrapping, scrollbar roles, and outer maximize geometry work; Wave 5 consolidates remaining chat state | Commands degrade, tabs are no-ops, moderation/channel state is wrong, and focus visuals diverge | `gmMainChatUI @ 0x004CCCC0..0x004CE2A0`; `UIElement_Scrollbar::OnSetAttribute @ 0x004714D0`; `ChatInterface` methods |

 | ~~AP-107~~ | **RETIRED 2026-07-11 (Wave 3.3 / #197)** — typed `OfferPrimaryClick` returns `NotActive`, `ConsumedSuccess`, or `ConsumedRejected`; every retained item surface plus radar/world offers active target mode before local selection/open/use fallback.

 | ~~AP-111~~ | **RETIRED 2026-07-11 (M2 held-object parenting)** — equipped hand items are no longer omitted from the render world. CreateObject now preserves Placement/Parent/position timestamp bootstrap; live `0xF749` ParentEvent is parsed with retail sequence freshness; a focused render controller resolves `Setup.HoldingLocations`, applies the child's placement frame, and recomposes the separate child entity after every parent animation tick.
