Olava tool calling, docx markdown bold, tabular UX

- Olava tool-call plumbing: switch to non-streaming when tools are
  forwarded (vLLM streaming with --enable-auto-tool-choice silently
  drops the parsed tool_calls payload, even though it sets
  finish_reason="tool_calls"). Single round-trip per iteration is
  more reliable.
- Custom client-side parser for the LoRA's <tool_call><function=...>
  <parameter=...> token format, generic across every tool. Iteratively
  strips trailing </parameter> / </function> / </tool_call> tags so
  values like read_document's docLabel aren't poisoned with markup.
  JSON-decodes parameter values, with scalar coercion fallback.
- generate_docx now parses **bold** markdown in section content via a
  small TextRun splitter so party names / defined terms render bold
  instead of leaking literal asterisks into the .docx.
- System prompt: demoted the "MUST call read_document after
  generate_docx" rule to "MAY", and explicitly forbids re-issuing
  generate_docx in the same turn to "fix" perceived imperfections -
  use edit_document or just describe the issue. Stops the model from
  emitting two duplicate downloads when it self-critiques.
- Tabular review: new "Wrap text" toolbar toggle (cells switch from
  line-clamp-1 to wrap-and-grow). Header columns are drag-to-reorder
  via HTML5 DnD, persisted through the existing columns_config saver;
  display order follows the array, cell lookup keeps using the stable
  .index. Per-column resize via a hidden right-edge drag handle with
  a 120px floor; widths are local state.
