Release v26.4.0

26.4.0

• LanguageTool ignored rules and ignored words are now persisted across
  application restarts; previously, ignored rules were only stored in memory and
  lost when the application was closed
  (for #3496)
• Added a new "Ignore word" option to the LanguageTool context menu that
  allows ignoring specific words (e.g. proper nouns, technical terms) without
  disabling the entire rule; ignored words are persisted across restarts
  (for #3496)
• Added "Reset ignored rules" and "Reset ignored words" buttons to the
  LanguageTool settings page to clear all previously ignored rules and words
  (for #3496)
• The last selected Nextcloud Deck card is now re-selected after the card
  list is reloaded when a card is stored or the archived cards view is toggled
  (for #3357)
• Fixed Nextcloud Deck card updating that caused HTTP 400 errors: the PUT
  request now uses the correct API v1.1 endpoint with the card's actual
  stackId in the URL path; the request body includes the required owner
  field (which the Deck server validates as mandatory), sends the card's real
  order value, always includes description, and explicitly sets duedate
  to null when no due date is selected; also fixed spurious QString::arg
  warnings in the error dialogs for card operations where placeholder indices
  were wrong, and added response body logging on errors for better diagnostics
  (for #3357)
• Added more Russian, German, Chinese Simplified, Korean, Spanish, French, Polish
  translation (thank you, pbek, VenusGirl, AlejandroMoc, jd-develop, Fresta24)
