v9.72 2026-06-26 WeKan ® release

This release fixes the following bugs:

• Fixed api.py addcustomfieldtoboard crashing on an empty settings argument. The CLI did
  settings = str(json.loads(sys.argv[6])), so json.loads('') raised JSONDecodeError and
  the command aborted before sending the request (a bug api.py's own header comment flagged).
  Empty settings now default to {} and are sent as valid JSON via json.dumps instead of
  str(dict) (which produced invalid JSON with single quotes). Verified that both empty and
  object settings (e.g. {"currencyCode":"EUR"}) create the custom field.
  Fixed in 487cf3f96.
• Mobile UI too large at All Boards and top bars,
  #6426: reverted the recent forced mobile
  2x/3x UI scaling rules that made All Boards and quick-access/header controls render oversized,
  while keeping the small-screen All Boards layout collapse so the left menu still stacks above
  the board grid on narrow screens.
  Fixed in f7a2a3ace5ebc6ac2c8ecef10a2d0477ab7b3e2c.
