feat(chargen): Campaign CC slice CC5 — Summary page, Finish flow, RandomizeCharacter port

Fills TS-82's Summary placeholder with a faithful port of gmCGSummaryPage
(name field with NameInputFilter + the retail commit-on-focus-lost/submit
dispatch + the >32-char ID_CharGen_NameTooLong reject-and-revert path, the
REAL three-row-template listbox confirmed against the installed EoR dat
before writing any page code, and Summary's own independent gmCG3DView
preview instance wired through a second ChargenPreviewController pair
mirroring the Appearance page's exact composition shape).

Ports CharGenState::RandomizeCharacter and its six sub-primitives into
RuntimeCharacterCreationState — not approximated: the RandInt/RollDice
semantics are independently confirmed from both the decompiled RNG bodies
and the CharGenStateVtbl union struct in acclient.h. Three consumers:
the chargen screen's open-roll (retiring AP-214's honest-blank deviation
and reproducing the Appearance page's gender-flip-on-init quirk), the
Summary page's Random button (behind the retail randomize-warning
confirm), and the Appearance page's Random button (narrowing AP-212 to
just Heritage/Profession/Town's still-approximated rolls and Skills'
still-unported RandomizeSkills).

Wires the Finish button (previously ghosted) with retail's NoName/
CreditWarning dialog pair, adds the F12 amendment's HeritageOrGenderUnset
local refusal to TryBeginFinish (register AP-223) as a defensive backstop
now that the screen-open roll normally makes it unreachable, and wires
the four ID_Character_Err_* rejection dialogs for the 0xF643 response
codes CC3 already parsed but nothing displayed.

Register: TS-82 retired, AP-214 retired, AP-212 narrowed, AP-223/224/225
filed (heritage/gender Finish refusal, Summary's two-bucket skill-list
narrowing, the 32-vs-33 name-length threshold reconciliation).

Runtime 1722/0 (was 1713), App 5240/3 skips (was 5223/3), Headless 166/0
unchanged, full solution Release build green.
