The save_as_pdf action now renders page metadata into the PDF margins by
default, matching Chrome's Print dialog: the date in the header and the page
URL plus page numbers in the footer.
- Add display_header_footer (default True), header_template, and
footer_template params to SaveAsPdfAction.
- Pass displayHeaderFooter + header/footer templates and explicit margins to
CDP Page.printToPDF so the metadata has room to render (Chrome clips it
otherwise, and defaults header/footer font-size to 0px).
- Default templates show the date / URL + page numbers; callers can override
with custom HTML or disable entirely for a clean PDF.
