HtmlTextBox now supports inline images through the "img" tag

NEW

• The HtmlTextBox report item now allows embedding images directly inside HTML‑formatted content using the "img" tag, including support for common attributes and basic styling. This enables seamless inline image rendering across all supported designers and output formats.

Paged report layout now supports repeatable table group headers/footers

NEW

• Table, Crosstab, and List items now include a PrintOnEveryPage property that allows static group headers/footers to repeat on every page the group spans. This improves readability when large groups extend across multiple pages.
