Bulk Apply Transaction Payment to Selected Invoices

Apply a single transaction payment to multiple selected invoices.

Supports two selection modes:

• Explicit invoice IDs (invoice_ids)
• Filter-based selection (filters) for "select all matching" behaviour

Reuses :meth:MarkInvoicePaidView.apply_transaction_payment so that line-level payment splitting, FX gain/loss realisation, and transaction cleanup are all respected. A single DraftQueue is created when approval is required.
