Kanban board does not enable horizontal scrolling when exceeding available width

[ACaminos]

When multiple columns are created in the Kanban board, the columns automatically shrink to fit within the visible screen width.
Currently, horizontal scrolling is not enabled, causing readability issues and making the board difficult to use.

Additionally, when a large number of columns are added, the board layout breaks entirely: columns overflow beyond the screen boundaries and become partially inaccessible, preventing users from viewing all columns properly.

Additional issue detected:
Because Kanban board columns become excessively compressed when many columns are added, the visual behavior of card and column dropdown/context menus is also affected.

When opening the options menu within the first narrow column:

The dropdown menu is clipped.
Part of the menu appears behind the sidebar.
Some menu items are not visible or accessible.

The z-index and/or positioning of the dropdown menu do not adjust correctly to the available space.
