tag_ids does nothing when creating a card via the API.

Summary

When trying create a card with tags via the Fizzy API, a card is created without tags.

Reproduce
POST https://fizzy.domain.com/<account_id>/boards/<board_id>/cards and add tag_ids to body with an array of existing tag ids (e.g. ['03fqnoac4bt5j9n2s2l2f3r92'])

Example body

{
  "card": {
    "title": "Some card title",
    "description": "<p>Some card description</p>",
    "tag_ids": ["03fqnoac4bt5j9n2s2l2f3r92"]
  }
}

Thanks for the report, @douwepausma!

You've found a real gap in the API. The card_params in CardsController only permits title, description, image, created_at, and last_active_at — tag_ids is not included, so it's silently dropped.

Tags are currently managed as a separate resource via Cards::TaggingsController, which toggles individual tags by title (not by ID). So the workaround today is to make separate POST requests to /<account_id>/cards/:card_number/taggings with tag_title for each tag after creating the card.
