feat(ui) Campaign CA CA4 #431: server-authoritative raises — the optimistic layer is deleted

Retail sends a raise and WAITS: one request in flight, the raise
controls ghost, and displayed state changes only when the authoritative
quality-change record lands (gmStatManagementUI @ 0x004F03F0 family,
pinned in docs/research/2026-07-10-retail-panel-behavior-pseudocode.md
§5, whose own conclusion names ApplyLocalRaise as the thing to remove).
The optimistic layer predates the inbound parsers — it existed so the
panel showed anything at all — and with CA2 delivering server truth it
became strictly harmful: against ACE, a wrong TrainSkill cost fails
SILENTLY, so the optimistic promote-and-debit could show a trained
skill the server refused with nothing to ever correct it.

Deleted: CharacterSheetProvider.ApplyLocalRaise + both spend helpers,
and LocalPlayerState's six optimistic mutators (ApplyAttributeRaise,
ApplyVitalRaise, ApplySkillRaise, ApplySkillTraining, DebitIntProperty,
DebitInt64Property) with their tests. Added: the one-in-flight latch in
HandleRaiseRequest, CharacterSheet.AwaitingRaise ghosting all raise
controls, and gate release on every authoritative quality signal
(attribute/character/player-property events unconditionally; vital
events only release-and-refresh while a raise is in flight, so regen
ticks stay out of the sheet-rebuild path). Panel unmount resets the
gate — retail's awaiting flag lives on the panel instance.

AP-73 NARROWS rather than retires: retail's release on a rejection that
produces NO quality change is statically unverifiable, and ACE sends
chat-only (Raise*) or nothing (RaiseSkill/TrainSkill) on failure; until
the CA5 live check, a silently-rejected request leaves the controls
ghosted until panel reopen — recorded with its observable symptom.

Also verified for CA4: the train button sends the DAT-exact TrainedCost
(ACE's silent exact-match rule), and there is correctly NO panel
specialize send — retail/ACE specialize only via the SkillAlterationDevice
item-use + confirmation round-trip, whose client seams
(SendConfirmationResponse 0x0275, the 0x028B WeenieErrorWithString chat
routing) already exist. Provider tests now pin the retail contract:
send-without-mutation, one-in-flight, release-on-record, release-on-
unmount, and the regen-tick rebuild guard. Full hermetic suite 15,327
passed / 0 failed.
