feat: add consolidated print backend route
Adds a new WWW page at /consolidated_printview that renders multiple documents of the same DocType in a single continuous HTML layout with no forced page breaks between records. - get_context() iterates over a JSON list of names, renders each doc via the existing get_rendered_template() pipeline (falls back to WeasyPrint for beta print-format-builder formats), and joins the results with a thin visual separator - Per-document page-break-after is suppressed via CSS override so all records flow as one uninterrupted printable page - trigger_print=1 fires window.print() automatically, matching the behaviour of the existing single-doc /printview route - Permission and render errors are caught per-document and logged so one bad record does not abort the whole batch - Access log entry recorded for auditing (first 10 doc names) Made-with: Cursor
