fix(studio): Character window — bind the REAL Attributes-tab elements (no guessing)

Redo of the character pilot per faithful-port rules. The previous pilot GUESSED a text
report and put it on the wrong window. The decomp (verified by dumping acdream's
importer-resolved tree) shows LayoutDesc 0x2100002E is the tabbed Attributes/Skills/Titles
window: its tab-content slot 0x1000022B mounts sub-layout 0x2100002C (gmAttributeUI) which
chains into the gmStatManagementUI header. The importer ALREADY mounts every content element
(FindElement resolves name 0x10000231, heritage 0x10000232, PK 0x10000233, level 0x1000023B,
total-XP 0x10000235, XP meter 0x10000236 → UiMeter, list box 0x1000023D) — EventId was a red
herring (the dat id lives in _byId, not the widget's EventId field).

CharacterStatController (port of gmStatManagementUI::UpdateCharacterInfo 0x004f0770 +
UpdateExperience 0x004f0a70 + UpdatePKStatus 0x004f00a0) binds those real elements: name,
heritage, PK status, level, total XP, the XP-to-level meter fill, and the six innate
attributes in the list box. Studio (--layout 0x2100002E) now renders the actual panel
content, not an overlay. 16 controller tests green; full App suite stays green.

Refinements with known decomp sources (follow-ups): tab-button active/inactive state so the
3 tabs draw their sprites; exact label wording from the StringTable (table 0x10000001 →
dat 0x31000001); the full AttributeInfoRegion row template (column-aligned values + raise
buttons). CharacterController (text-report 0x2100001A) retained for that separate sub-panel.
