fix(ui): #409 tooltip review fix round — F1-F11

Opus review of a377b9bf returned architectural PASS-with-findings /
retail-fidelity FAIL with F1-F12 (F12 info-only). All eleven fixed,
each re-derived against docs/research/named-retail/acclient_2013_pseudo_c.txt:

- F1 PositionAtMouse: retail offsets BOTH axes +32px before the clamp
  (StartTooltip @0x00459700, @0x00459739/@0x00459747) — was landing
  flush at the cursor.
- F2 UiRoot: the dwell timer now anchors to mouse-IDLE like retail's
  m_lastMouseMoveTime (MouseMoveHandler @0x0045E710), resetting on
  every move within the same widget while !_tooltipFired, not just on
  hover-enter.
- F3 register TS-85 rewritten: the "dynamic InqProperty(0x49) override"
  framing was false — UIElement::InqProperty @0x004638D0's base impl
  reads the same authored bags this port already reads. The real
  second text source (m_TTText/SetTooltip, headed by the P0xD0
  truncated-text auto-tooltip @0x00466F80) needs a per-line-position
  truncation model UiText doesn't have — sized disproportionate for
  this round and left honestly deferred rather than stubbed.
- F4 OnTooltipShow: null LayoutPolicy + Anchors=None on the popup root
  and text child before resizing, mirroring RetailMessageDialogView's
  sibling shape.
- F5 OnTooltipShow: return without mounting when the P0x4A text child
  doesn't resolve to a UiText (retail's DynamicCast gate,
  StartTooltip @0x0045DE90 @0x0045df65/@0x0045df6f) — was mounting an
  empty 30x30 bevel artifact.
- F6 UiRoot.Tick: the dwell-arm branch now requires Captured is null
  (CheckTooltip @0x0045B6E0 @0x0045b715) — a widget hovered before a
  drag/resize/capture began must not pop mid-gesture.
- F7 UiRoot.ReleaseCapture: no longer resets _tooltipFired
  (ReleaseMouseCapture @0x0045D2B0 touches only the idle timestamp) —
  a mouse-up while a tooltip is shown no longer tears it down and
  silently re-fires it 250ms later.
- F8 ApplyTooltipText: applies ResizeTo's own max/min width/height
  clamps (P0x3C/0x3D/0x3E/0x3F, @0x00463C30) before assigning the
  grown size; zeroes text.Padding to keep the measured size margin-
  comparable. New ElementInfo/UiElement plumbing for the four
  properties, same shape as the existing tooltip fields.
- F9 doc precision: sweep counts corrected 434->430 / 191->187 (live-
  DAT re-measured), the "243 showable" claim now measured exactly
  (not assumed) via a new Showable column in the sweep test, and the
  MiscSettings citation split into its two real mechanisms
  (RegisterPreference in Init vs. AttachPreference/SetPreferenceRange
  elsewhere).
- F10 register AD-106: the topmost guarantee is versus dialogs/screens
  only (the overlay popup layer and drag ghost still paint above
  regardless), and the per-tick BringToFront ratchet has four rungs,
  not three.
- F11 RetailUiRuntime.ResetSessionDialogs: now also calls the new
  UiRoot.ResetTooltipTracking() so a post-reset hover re-shows
  immediately instead of waiting out the stale fired-latch.

New pinning tests (RetailTooltipPresenterTests: F1/F2/F5/F6/F7/F8) each
verified to fail against the pre-fix behavior via a temporary revert-
and-rerun before being confirmed against the restored fix.
