docs(CT): CT1 fix round — sealed RowHighlightSprite verdict, verified resize mechanism, strengthened pins

Applies the Opus dual-lens review corrections to CT1's DAT ground-truth
research (docs/research/2026-08-24-campaign-ct-dat-ground-truth.md):

- Window constraints (BLOCKER): replaced the "likely a hardcoded
  ResizeTo/SetMinSize" guess with the verified mechanism —
  UIElement::ResizeTo clamps only via element attributes 0x3C-0x3F,
  nothing writes them at runtime, and retail resizes the SHARED
  gmPanelUI host (LayoutDesc 0x2100006E, slot 0x1000018E) rather than
  0x2100002E's own content root. Flags the unresolved 300x600-vs-300x362
  size tension for CT3/CT6 and marks the host elements NOT PROBED by
  CT1.
- RowHighlightSprite upgraded from a flagged hedge to a SEALED VERDICT:
  the stat row's selected-state media is 0x06000F93
  (gmAttributeUI::UpdateSelection -> InfoRegion::SetState on template
  0x10000248), not 0x06001397 (which is legitimately the spellbook
  row's separate selected-overlay mechanism). Falsifies the matching
  comment in CharacterStatController.cs and dated-corrects the older
  2026-06-26 doc at the spot that originated the wrong sprite id.
- Replaced the "18px gutter + 7px = 25px" derived story with the bare
  authored rectangles (the numbers don't compose cleanly: 300-281=19,
  and the 282px row overlaps the 281px scrollbar band by 1px) — CT5
  must implement the authored numbers directly, never a derived
  listWidth-18 formula.
- Plan doc: corrected the UpdateButtons ghost rule (no selection ->
  Ghosted, not "ghosts when selected == current") and added the
  AddTitleToList row-write contract for CT3.
- Pins: CharacterPanelLiveDatTests now honors ACDREAM_DAT_DIR first
  (matching InstalledDatFactAttribute and its sibling live-DAT test
  classes), hoists five vacuous bare-foreach assertions to counted
  .ToList() pins, and adds the stat ListBox + scrollbar rect pins that
  CT5/CT6 depend on.
- Doc hygiene: marked several probe-session observations (header
  geometry "identical" claim, 0x06004CC2 characterization, the
  master-map/category-map dump) as unpinned inference vs. committed
  fact, corrected the 0x1000052D "throwaway container" mislabel, and
  stated the header table's parent-relative coordinate frame.
- Recorded the CT5 gold this round found: InfoRegion::InfoRegion's
  icon-DID lookup (a third GetDIDByEnum consumer, category
  0x10000002) and gmSkillUI::RebuildSkillList's section-header order
  confirmation, plus the RowHeight=22-vs-authored-20 divergence for
  attribute rows.

Verified: ACDREAM_RUN_INSTALLED_DAT_TESTS=1 CharacterPanelLiveDatTests
filter 9/9 green; hermetic App suite filter (CI's Lane exclusion list)
6111/6111 green. No production code changed.
