Add Vertical View for Better Card Organization and Overviewiew for Better Card Organization and Overview

The current horizontal layout of Nextcloud Deck, where lists are arranged side-by-side, doesn't efficiently utilize the vertical space of most widescreen monitors. This limits the number of cards visible at once, especially in expanded view, making it difficult to get a good overview of a project and prioritize tasks effectively.

I would like to see a vertical view option in Nextcloud Deck. In this view:

Cards would be arranged horizontally from left to right within each list.
Lists would be stacked vertically on top of each other.
This would make better use of the screen real estate and allow users to see more cards simultaneously, even when expanded. It would also make it easier to arrange cards vertically by priority or importance within each list.

Horizontal Scrolling: While possible, horizontal scrolling is not an efficient way to navigate through many lists, especially when dealing with numerous cards.
Zooming Out: Zooming out reduces card size and makes it harder to read information and interact with them.
External Tools: Using external Kanban tools with vertical layouts is an option, but it would be preferable to have this functionality integrated directly into Nextcloud Deck.
Additional context

A vertical view option would significantly improve the user experience for those who prefer to visualize their workflow vertically or have widescreen monitors. This layout is a common feature in many other Kanban tools and would make Nextcloud Deck more versatile and adaptable to different user preferences and project needs.

Start by tracing Nextcloud Deck's board, list, and card rendering entry points to understand how the current horizontal layout is assembled. Define how users switch to the vertical view, then implement stacked lists with horizontally arranged cards and verify that the option works with expanded cards and many lists.
