feat(ui): House tab ownership text — DisplayPurchaseTimeText + RuntimeHouseState

Derived the mechanism from the decomp before writing code: neither
gmHouseUI::PostInit @0x004a2710 nor gmMapUI::PostInit @0x004a1c70 sends a
HouseQuery, and six of gmHouseUI's seven Display* builders early-return on
m_pHouseData == 0. The only text a houseless character's House tab shows is
gmHouseUI::DisplayPurchaseTimeText @0x004a3110's expired branch (it doesn't
gate on m_pHouseData) — the local player's PropertyInt.HousePurchaseTimestamp
plus HouseSystem::HasPurchaseWaitPeriodExpired renders exactly "You may buy
another house immediately." for a fresh character. Exhaustive search of the
2013 EoR decomp, ACE, and the live DAT found zero support for a second
"You do not currently own a house." line the task brief described — this
commit ports what the decomp actually shows.

Ships:
- RuntimeHouseState: a minimal (no disposal, no construction-transaction
  Fault() point) Runtime owner per ISSUES #413's own sizing note, wired
  through GameEventWiring's existing HouseData/HouseStatus delegate holes,
  LiveSessionEventRouter, and GameRuntime.HouseOwner. Participates in
  RuntimeGenerationReset (new House stage) since a fresh login must not
  show a stale character's house state.
- HousePageController.Bindings.Lines/OnShown wired to real data; OnShown
  fires WorldSession.SendHouseQuery() on tab-open (AD-107: an acdream
  trigger, not a ported retail call site — filed in the divergence
  register).
- Fixed a real bug found along the way: HousePageController.Bind never
  wired UiTemplateListBox.TemplateResolver, so no row could ever render
  regardless of Lines content. Now reuses the Map tab's generic hotspot
  resolver.

Live-verified against a real local ACE server and the +Acdream character
(--session-config auto-select + a UI automation script): screenshot and
structural UI-tree dump both confirm the House tab renders exactly "You may
buy another house immediately." Graceful logout confirmed both launches.

ISSUES #413 narrowed to its one remaining piece: the six owned-house-only
Display* builders (DisplayBuyPayment/RentPayment/BuyTime/RentTimes/
Location/WarningText), unexercisable without a test character that owns a
house.
