Chris Chen d9289008f6 feat(expense): add ExpenseService with state machine + receipt storage + tests
TDD: wrote 8 tests first (red), then implemented IExpenseService + ExpenseService
covering CRUD, Draft→PendingApproval→Approved→Paid state machine, soft-delete,
per-owner access guards, and receipt blob round-trip via IFileStorage.
