Use html3pdf instead of html2pdf.js to avoid canvas overflow

[Arcticn]

• scale changed from 2 to 3 to output a clearer pdf
• change html2pdf.js to html3pdf to avoid canvas overflow
• apply a patch for html3pdf to patch the newest pull request which adds pagesPerCanvas option to speed up generate
• auto-detect userAgent to set a proper pagesPerCanvas option (only tested with Firefox127 - 9 , Chrome & Edge 126 - 19). So I set 9 for default but 19 for Chromium browsers
• add onProgress event to let users learn the progess of generation
• fix code not wrap in pdf and remove incorrect row numbers
