EU CAMT.053 Import

Multi-statement and prefixed-namespace files. A daily CAMT file often carries several Stmt blocks, one per bank account. The importer now creates one Odoo bank statement per block, each with its own IBAN, its own opening/closing balance and the bank journal matched from that block’s IBAN — and it writes the journal on every statement line, which is where Odoo reads it from. Files that bind the ISO 20022 namespace to a prefix (ns2:Document…) are read exactly like default-namespaced ones, and a file that declares no ISO 20022 namespace at all is refused with a clear message instead of a technical XML error. Important correction: earlier versions put every movement of the file into a single statement, with the balances of the first block only and the journal that Odoo picked by default rather than the one you selected — if you imported files covering more than one bank account, review those statements. The upgrade keeps the statement each file already produced and adds the new «Statements created» list; nothing already booked is rewritten.
