Add option to keep Tabs block headers horizontal/inline on mobile devices

Requested feature

Currently, the Otter Tabs block displays tabs as a single vertical column on mobile. Users need an option to keep tabs horizontally aligned (inline) on both desktop and mobile, or at least grouped horizontally at the top. This would improve mobile usability for sites rebuilt with the Block editor using Otter Blocks.

Customer context

I have Neve PRO and am rebuilding all my site's pages, which were built with the Classic editor, with the Block editor. To do this, I'm trying to make the most of OTTER blocks. For Tabs, I haven't found a way to keep the tabs inline on mobile, but they are displayed as a single column. Is there a way to ensure that the tabs remain horizontally aligned on both desktop and mobile, or at least grouped at the top?

Start by locating the Otter Tabs block implementation and its responsive styling or configuration entry points; no specific files or tests are named in the issue. Trace how the tabs switch to a vertical layout on mobile, then define the option's behavior for horizontal alignment and verify it on desktop and mobile views.
