Loan Accounts

Prepay loan account (BR alias)

BR-aliased path for prepaying a loan account. Resolves to the same handler as the core endpoint, with the jurisdiction resolver inserted into the chain. BR accounts require quoteId; when amount is also provided, it must equal the quote's net settlement amount. Idempotency is enforced by the lib-commons idempotency middleware via the X-Idempotency header; a reused key with different facts yields 409. A missing quote, malformed UUID, or invalid amount yields 422.
