[CLAUDE] App: golive harden — LeaveBalance concurrency + ItTicket authz-order + DocxRenderer + Travel/Vehicle tests

Pre-golive verification (S56) surfaced 4 issues; all fixed + verified (228 test pass, 0 build warning).

#3 LeaveBalance lost-update (DB11 concurrency): terminal-approve deduction was an in-memory read-modify-write (UsedDays += NumDays) under a bare SaveChanges, so two concurrent terminal approvals of the same (user,type,year) lost an update. Fix: atomic server-side ExecuteUpdateAsync (UsedDays = UsedDays + n) inside an explicit Serializable transaction (matches the codegen/Proposal/TravelVehicle convention; serializes the auto-create-row race too). Exactly-once guard (Status != DaGuiDuyet) intact. No migration.

#5 ItTicket reassign existence-oracle: AssignItTicketHandler checked ticket-NotFound before the Admin-OR-dept-IT Forbidden guard. Reordered so authorization runs first -> fail-closed (a non-IT/non-admin caller gets Forbidden for any ticketId, existent or not).

#6 DocxRenderer CS8602: null-guard MainDocumentPart + Document with clear exceptions (cleared 2 build warnings -> 0).

#4 Travel/Vehicle ApproveV2: added smoke tests (Submit->Approve terminal + outsider-Forbidden) — previously zero coverage.

Tests 216 -> 228 (+12). database-agent DB-layer review PASS; em-main cross-stack review clean (reviewer workflow stage did not emit StructuredOutput -> em-main covered the cross-stack review by reading every diff). Bundles agent-memory harvest (S56).

User-unchanged is a POSITIVE signal here (mirror of BE-only Run #243/#368 where admin+user both stay frozen). Visual-only redesign (CSS tokens + className) rotates bundle exactly like logic change — Vite content-hash byte-sensitive. Status-grep gotcha: greedy `.*?` regex failed to isolate `"status"` field mid-poll → use `grep -oE '\\{"id":378,[^}]*\\}'` to capture full object then sub-grep status.
