docs: literature references

[slayoo]

• check presence of a bibliography JSON file:
  • DOI labels as main dictionary key
  • "usages" key pointing to a list of project files in which the ref is mentioned
  • "label" field like "Magnuszewski et al. 2025"
  • "title", "year", "authors" fields - as in bib files
  • "note" field explaining how and why the ref is used
• html/jinja file with JS code downloading the JSON and rendering it (as in https://stackoverflow.com/questions/29538002/how-to-load-json-file-to-a-html-table-using-javascript)
• new devops tests featuring:
  • loading the JSON bib file
  • scanning all-but-bib.json files in the repo for HTML or Markdown DOI links incl. generation of "usages" (with files and labels)
  • comparing is the scan results are consistent with DOI keys, labels and "usages" in the bib JSON file (as in https://github.com/open-atmos/PySDM/blob/main/tests/examples_tests/test_tests_completeness.py)
• for future:
  • matching DOIs with titles, authors and other metadata from http://dimensions.ai/
  • dimensions.ai badges in the HTML refs page?
