Adds an "Add expense" action to the expenses ledger for costs with no inbound
document — mileage, per-diem, a cash receipt, etc.
- accounting.service: createExpense() -> POST /admin/expenses
(createManualExpense); CategorizePayload gains `description`.
- ExpensesLedgerPage: AddExpenseModal with supplier / description / amount /
currency / disposition (company expense / pass-through / re-bill — no
duplicate, there's no document to dedupe). Company-expense picks a category;
re-bill uses the customer picker + markup and chains createExpense -> rebill
into an editable scheduled invoice, same as inbox triage. "Add expense"
button in the filter row.
- i18n: accounting.ledger.{addExpense,addTitle,description,descriptionHint,
createdToast} (EN + DE); shared field labels reuse accounting.inbox.field.*.
Verified: en/de JSON valid; npm run build green.
