v1.23

Fix table/box rendering, support native table numbering, localize callouts

• Recognize continuation paragraphs inside boxes indented with 3 spaces
  (extracts lose one space of indentation when converted to asides),
  fixing dropped "Antwort" paragraphs in Q&A-style boxes.
• Rewrite I>/T>/W> callouts block-wise so a multi-paragraph callout gets
  one title instead of one per line, and stray >/I>/T>/W> markers no
  longer leak into the rendered output.
• Make callout titles (NOTE/TIP/WARNING) configurable per template via
  new note_title/tip_title/warning_title settings, defaulting to
  the previous English words; set to Hinweis/Tipp/Warnung for the
  dpunkt templates.
• Support unnumbered Table: Caption {#tbl:...} captions so
  pandoc-crossref can auto-number and auto-link tables the same way it
  already does for figures and listings; exclude such captions from the
  generic paragraph-wrapping rules so they stay adjacent to their table
  block, which pandoc-crossref requires to recognize the pairing.
• Move numbered-table anchors onto the caption's own div so
  pandoc-crossref cross-references resolve to real bookmarks, and
  captions no longer show literal {#tbl:...} braces in the output.
• Fix numbered-table cross-reference links losing the dash before the
  slug (#tbl:7.1bewertung... instead of #tbl:7.1-bewertung...).
