feat(world): the login wormhole — every world entry runs retail's portal-space presentation with sound (TS-28 narrowed)

Retail runs the SAME TAS_TUNNEL wormhole at initial login as at an F751
teleport, with no F751 involved: SmartBox::teleport_in_progress
@0x00451C20 returns 1 the moment the login player exists with
position_update_complete == 0, gmSmartBoxUI::UseTime @0x004D6EAB
edge-detects it into BeginTeleportAnimation(TAS_TUNNEL) @0x004D6EC9
(playing Sound_UI_EnterPortal @0x004D638E), SmartBox::UseTime
@0x00455483 ends the hold once destination cells stop blocking,
Sound_UI_ExitPortal plays at the viewport swap @0x004D7405, and
LoginComplete goes out at the WorldFadeIn end @0x004D745D ->
CPlayerSystem::SendLoginCompleteNotification @0x00562E90 (ACE's own
GameActionLoginComplete comment names this contract: 'called when the
client player exits portal space. It includes initial login'). acdream
skipped all of it at login — every entry route (direct auto-select,
character-select Enter, enter-after-create) dropped onto the sky-only
'waiting for login' backdrop until the world reveal completed.

The fix engages the EXISTING F751 presentation machinery on Runtime's
login reveal — no duplicated presentation code, no timers:

- LocalPlayerTeleportController gains a login arm keyed off the
  Runtime-owned login reveal generation (RuntimeWorldTransitState
  .BeginLoginReveal, begun on the first accepted local-player position
  on every entry route). It drives the same TeleportAnimSequencer/
  PortalTunnelPresentation lifecycle and the same enter/exit cues; the
  Place edge is a no-op at login (the first-entry conductor already
  committed the canonical placement — retail's analogue only flips
  position_update_complete), and FireLoginComplete now performs
  EnterWorld + the single LoginComplete send + reveal Complete, exactly
  like the F751 pump. worldReady is latched on BOTH canonical first
  placement (OnLocalPlayerFirstEntryCompleted, the repointed
  GraphicalSessionEventRoute completion callback that used to send
  LoginComplete immediately) AND destination reveal readiness.
  ActiveDestinationCell now also reports the login destination so the
  render frame's reveal-preparation arm keeps running after portal-space
  entry flips ChaseModeEverEntered.
- PlayerModeController.TryEnterPortalSpaceForLogin performs the
  player-mode presentation attach (the same BuildControllerAndCamera the
  post-reveal auto-entry used to run) before flipping into portal space
  — at login no player-mode entry has happened yet. TryEnterPortalSpace
  itself now refuses (retryable) on a constructed-but-unpublished
  Runtime controller via the documented CanExecuteLiveMovement skip
  predicate instead of faulting — the first connected run crashed on
  exactly that pre-publication State write.
- HouseQuery stays at first-entry completion (retail: tail-called from
  CPlayerSystem::InitializePlayer @0x00563570, an object-arrival edge,
  not a tunnel edge).
- An F751 arriving mid-login-tunnel withdraws the login claim and hands
  the presentation to the portal pump, which owns the single
  LoginComplete — matching retail's one teleportInProgress flag.

TS-28 narrowed: the graphical host now runs the full login wormhole;
the residual is headless-only (no presentation; placement-edge send).

Live gates (testaccount2/+Horan vs local ACE, Release): the
character-select Enter route and the --session-config direct auto-select
route both play the wormhole with Sound_UI_EnterPortal at animation
begin, hold with retail's 'In Portal Space - Please Wait...' notice
until readiness, fade out with the view-plane warp, send LoginComplete
at the WorldFadeIn end, and materialize in Holtburg; ACE-confirmed
graceful logout. Tests: App 5493/3 skips (baseline 5490 + 3 new login
tests), Runtime 1744/0, full solution green.
